telemetry: fix port stats retrieval

The ep struct is used to track what type of stats are required by the
client. For PORT_STATS type, it contains the lists of port and metric
ids to query, and the number of ids in each list.

The ep struct has values set (num of port and metric ids) when a request
for port stats values by name is received. However, after this value
assignment, the struct is reset to all 0 values, meaning the number of
port and metric ids required now both show as 0, and the client will not
receive the requested data in response. To fix this issue, the memset
call is now moved above the ep struct value assignment.

mem: mark pages as not accessed when reserving VA

When the memory allocator reserves virtual addresses, it still does not

Besides, huge areas are reserved for memory hotplug in multiprocess

Change protection mode to PROT_NONE when only reserving VA.

vdpa/mlx5: fix guest notification timing

When the HW finishes to consume the guest Rx descriptors, it creates a
CQE in the CQ.

The mlx5 driver arms the CQ to get notifications when a specific CQE
index is created - the index to be armed is the next CQE index which
should be polled by the driver.

The mlx5 driver configured the kernel driver to send notification to the
guest callfd in the same time it arrives to the mlx5 driver.

It means that the guest was notified only for each first CQE in a poll
cycle, so if the driver polled CQEs of all the virtio queue available
descriptors, the guest was not notified again for the rest because
there was no any new cycle for polling.

Hence, the Rx queues might be stuck when the guest didn't work with
poll mode.

Move the guest notification to be after the driver consumes all the
SW own CQEs.
By this way, guest will be notified only after all the SW CQEs are
polled.
