net/bnx2x: fix FW command timeout during stop

Browse Source 
This patch fixes firmware command timeout error seen during device stop
while stopping queues. It patially reverts an earlier preventive change
commit 91b7e432bcef ("net/bnx2x: disable fast path interrupts") to now
enable fast path interrupts.

The original issue of performance degradation is not observed anymore,
with or without the fix.
