nvme: Fix spurious interrupts

The code had asserted an interrupt every time it was requested to check
for new completion queue entries.This can result in spurious interrupts
seen by the guest OS.

Fix this by asserting an interrupt only if there are un-acknowledged
completion queue entries available.
