nvme: fix admin queue leak on controller reset

Browse source

[ Upstream commit b84bb7bd91 ]

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 03b3bcd319 ("nvme: fix
admin request_queue lifetime").
