The interrupt handler clears the interrupt status register for response
updates in the base queue while working in the multique mode. This could lead
to missing interrupt for async events, mail box completions etc. as these are
also handled in the base queue.  The fix ensures that the interrupt bit is not
cleared for response updates in the ISR when the driver is working in
multiqueue mode.
