[PATCH 8/9] NVMe: Set queue db only when queue is initialized

[Keith Busch]

There is no need to set it when the queue is allocated as it can't be
used until it is created in the controller. We may initialized a queue
multiple times, but allocate it only once, so we have to set the queue
doorbell address each time it is initialized.
