block: Remove redundant WARN_ON()

Commit 2fff8a9 ("block: Check locking assumptions at runtime") added a lockdep_assert_held(q->queue_lock) which makes the WARN_ON() redundant because lockdep will detect and warn about context violations. The unconditional WARN_ON() does not provide real additional value, so it can be removed.
