block: add lockdep to queue_limits_commit_update()
queue_limits_commit_update() expects q->limits_lock to be held by
the caller (via queue_limits_start_update()).
The API pattern is:
lim = queue_limits_start_update(q); /* acquires lock */
/* modify lim */
queue_limits_commit_update(q, &lim); /* releases lock */
OR
queue_limits_commit_update_frozen(q, &lim);
lim = queue_limits_start_update(q); /* acquires lock */
queue_limits_commit_update(q, &lim); /* releases lock */
Add lockdep_assert_held() to report incorrect API usage.
