nvme-pci: fix queue unquiesce check on slot_reset

A zero return means the reset was successfully scheduled. We don't want
to unquiesce the queues while the reset_work is pending, as that will
just flush out requeued requests to a failed completion.

Fixes: 71a5bb153be104 ("nvme: ensure disabling pairs with unquiesce")
