Keith Busch 604e8c8da8 NVMe: reap completion entries when deleting queue ...

Make sure that there are no unprocesssed entries on a completion
queue before deleting it, and check for validity of the CQ
door bell before writing completions to it.

This fixes problems with doing a sysfs reset of the device while
it's handling IO.
