scsi: lpfc: Fix NMI watchdog assertions when running nvmet IOPS tests

Browse source

After running IOPS test for 30 second we get kernel:NMI watchdog:
Watchdog detected hard LOCKUP on cpu 0

The driver is speend too much time in its ISR.

In ISR EQ and CQ processing routines, if we hit the entry_repost numbers
of EQE/CQEs just break out of the routine as opposed to hitting the
doorbell with NOARM and continue processing.
