[patch 04/14] locking/rtmutex: Consolidate rt_mutex_init()

[Thomas Gleixner]

From: Sebastian Andrzej Siewior <bige...@linutronix.de>

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.
