ixl(4): Add link state polling

In some cases driver may ask FW about link state before FW finishes
configuration of a (Q)SFP+ transceiver. If first attempt of using Get Link
Status AQC after loading driver or handling a reset fails, then re-try
periodically for 5 seconds.

ixl(4): Fix reporting of unqualified transceivers

When link_active_on_if_down flag is disabled and link is brought down
with ifconfig, FW reports a false positive link event about an
unqualified transceiver. The condition used in the driver to filter out
those false positive events was incorrect and caused that unqualified
module event to also not be reported when the event was valid.

Change the condition to rely on IFF_UP flag instead of
link_active_on_if_down and bump driver version to 2.3.1-k.

ixl(4): Fix VLAN HW filtering

X700 family of controllers has limited number of available VLAN
HW filters. Driver did not handle properly a case when user
assigned more VLANs to the interface which had all filters
already in use. Fix that by disabling HW filtering when
it is impossible to create filters for all requested VLANs.
Keep track of registered VLANs using bitstring to be able
to re-enable HW filtering when number of requested VLANs
drops below the limit.

Also switch all allocations to use M_IXL malloc type
to ease detecting memory leaks in the driver.
