locking: Remove rt_rwlock_is_contended().
rt_rwlock_is_contended() has no users. It makes no sense to use it as
rwlock_is_contended() because it is a sleeping lock on RT and
preemption is possible. It reports always != 0 if used by a writer and
even if there is a waiter then the lock might not be handed over if
the current owner has the highest priority.
Remove rt_rwlock_is_contended().
