block: move q_usage_counter release into blk_queue_release

mainline inclusion
from mainline-v5.18-rc1
commit ba3e8456
category: bugfix
bugzilla: 187268, https://gitee.com/openeuler/kernel/issues/I5N162

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ba3e845665fbbb0252336f27200cd5cf288a3573



----------------------------------------

After blk_cleanup_queue() returns, disk may not be released yet, so
probably bio may still be submitted and ->q_usage_counter may be
touched, so far this way seems safe, but not good from API's viewpoint.

Move the release q_usage_counter into blk_queue_release().
