scsi: megaraid_sas: Handle missing interrupts while re-enabling IRQs
While reenabling the IRQ after IRQ poll there may be a small window for the
firmware to post the replies with interrupts raised. In that case the
driver will not see the interrupts which leads to I/O timeout.
This issue only happens when there are many I/O completions on a single
reply queue. This forces the driver to switch between the interrupt and IRQ
context.
Make the driver process the reply queue one more time after enabling the
IRQ.
