Subject: nvme: loop: clear NVME_CTRL_ADMIN_Q_STOPPED after admin queue is
reallocated
Patch-mainline: v5.16-rc1
Git-commit: 1d35d519d8bf224ccdb43f9a235b8bda2d6d453c
References: bsc#1201651
The nvme-loop's admin queue may be freed and reallocated, and we have to
reset the flag of NVME_CTRL_ADMIN_Q_STOPPED so that the flag can match
with the quiesce state of the admin queue.
nvme-loop is the only driver to reallocate request queue, and not see
such usage in other nvme drivers.
