From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>
We added code to restock the buffer upon ALIVE interrupt
when MSI-X is disabled. This was added as part of the context
info code. This code was added only if the ISR debug level
is set which is very unlikely to be related.
Move this code to run even when the ISR debug level is not
set.
Note that gen2 devices work with MSI-X in most cases so that
this path is seldom used.
