block: Remove redundant WARN_ON()

Commit 2fff8a924d ("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.
