net/mlx5: fix Rx interrupts management

This commit addresses various issues that may lead to undefined behavior
when configuring Rx interrupts.

While failure to create a Rx queue completion channel in rxq_ctrl_setup()
prevents that queue from being created, existing queues still have theirs.
Since the error handler disables dev_conf.intr_conf.rxq as well, subsequent
calls to rxq_ctrl_setup() create Rx queues without interrupts. This leads
to a scenario where not all Rx queues support interrupts; missing checks on
the presence of completion channels may crash the application.

Considering that the PMD is not supposed to disable user-provided
configuration parameters (dev_conf.intr_conf.rxq), and that these can
change for subsequent rxq_ctrl_setup() calls anyway, properly supporting a
mixed mode where not all Rx queues have interrupts enabled is a better
approach.

To do so with a minimum set of changes, priv_intr_efd_enable() and
priv_create_intr_vec() are first refactored as a single
priv_rx_intr_vec_enable() function (same for their "disable" counterparts).
Since they had to be used together, there was no point in keeping them
separate.

Remaining changes:

- Always clean up before reconfiguring interrupts to avoid memory leaks.
- Always clean up when closing the device.
- Use malloc()/free() instead of their rte_*() counterparts since there is
  no need to store the vector in huge pages-backed memory.
- Allow more Rx queues than the size of the event file descriptor array as
  long as Rx interrupts are not requested on all of them.
- Properly clean up interrupt handle when disabling Rx interrupts (nb_efd

- Check completion channel presence while toggling Rx interrupts on a given

mem: do not advertise physical address when no hugepages

When populating a mempool with a virtual memory area, the mempool
library expects to be able to get the physical address of each page.

When started with --no-huge, the physical addresses may not be available
because the pages are not locked in memory. It sometimes returns
RTE_BAD_PHYS_ADDR, which makes the mempool_populate() function to fail.

This was working before the commit cdc242f260e7 ("eal/linux: support
running as unprivileged user"), because rte_mem_virt2phy() was returning
0 instead of RTE_BAD_PHYS_ADDR, which was seen as a valid physical
address.

Since --no-huge is a debug function that breaks the support of physical
drivers, always set physical addresses to RTE_BAD_PHYS_ADDR in memzones
or in rte_mem_virt2phy(), and ensure that mempool won't complain in that
case.

mk: require SSE4.2 support on all x86 platforms

Increase the default baseline from "core2" architecture to "corei7". This
means that all builds will have SSE4.2 support included, and we can remove
special case manipulation of CFLAGS for the same. Naturally, this does mean
that some machines that previously could run DPDK now can't do so, but
hardware with SSE4.2 has been around for almost a decade now, so this
should not be a major problem.

Don't zero the pages during each mmap. Instead, only zero the pages
when they are not already mmapped. Otherwise, the multi-process
support will be broken, as the pages will be zeroed when secondary
