crypto/qat: separate sym-specific from generic qp setup

Extracted all sym-specific code from qp setup fns, leaving
generic qat_qp_setup fn and helper fns. Created a new
meta-data struct qat_qp_config to hold all the data needed
to create a qp, filled this out in the sym-specific code
and passed to the generic qp_setup fn.
No need now for rx and tx queue_create fns, one generic
queue_create fn replaces these.
Included the service name (e.g. "sym") in the qp memzone

igb_uio: fail and log if kernel lock down is enabled

When EFI secure boot is enabled, it is possible to lock down kernel and
prevent accessing device BARs and this makes igb_uio unusable.

Lock down patches are not part of the vanilla kernel but they are
applied and used by some distros already [1].

It is not possible to fix this issue, but intention of this patch is to
detect and log if kernel lock down enabled and don't insert the module
for that case.

The challenge is since this feature enabled by distros, they have
different config options and APIs for it. This patch is done based on
Fedora and Ubuntu kernel source, may needs to add more distro specific
support.

net/bonding: always update bonding link status

When the first ETH_LINK_UP slave is added to a bonding device, it is
immediately activated.  If these are polling slaves, there will be a
later link state event, when last_link_status doesn't match link_status.
But because this slave is already activated, the bonding device's link
status isn't updated.

To fix this, we always attempt to update the bonding device's link status
in the link state change callback.
