locking/mutex: Fix non debug version of mutex_lock_io_nested()

commit 291da9d4a9eb3a1cb0610b7f4480f5b52b1825e7 upstream.

If CONFIG_DEBUG_LOCK_ALLOC=n then mutex_lock_io_nested() maps to
mutex_lock() which is clearly wrong because mutex_lock() lacks the
io_schedule_prepare()/finish() invocations.

Map it to mutex_lock_io().
