locking/rtmutex: Consolidate rt_mutex_init()
rt_mutex_init() only initializes lockdep if CONFIG_DEBUG_RT_MUTEXES is
enabled, which is fine because all lockdep variants select it, but there is
no reason to do so.
Move the function outside of the CONFIG_DEBUG_RT_MUTEXES block which
removes #ifdeffery.
