nvme: fix admin queue leak on controller reset
[ Upstream commit b84bb7bd913d8ca2f976ee6faf4a174f91c02b8d ]
When nvme_alloc_admin_tag_set() is called during a controller reset,
a previous admin queue may still exist. Release it properly before
allocating a new one to avoid orphaning the old queue.
This fixes a regression introduced by commit 03b3bcd319b3 ("nvme: fix
admin request_queue lifetime").
