qlcnic: Fix mailbox completion handling during spurious interrupt
[ Upstream commit 819bfe764dceec2f6b4551768453f374b4c60443 ]
o While the driver is in the middle of a MB completion processing
and it receives a spurious MB interrupt, it is mistaken as a good MB
completion interrupt leading to premature completion of the next MB
request. Fix the driver to guard against this by checking the current
state of MB processing and ignore the spurious interrupt.
Also added a stats counter to record this condition.
