[PATCH] Real-Time Preemption V0.7.52-07: rt_init_MUTEX_LOCKED declaration

[Luca Falavigna <dktrkranz@gmail.com>]

This patch fixes broken rt_init_MUTEX_LOCKED declaration using rt_sema_init()
macro. This way we fix a potential compile bug: rt_init_MUTEX_LOCKED calls
there_is_no_init_MUTEX_LOCKED_for_RT_semaphores, which is not referenced.
(e.g. drivers/char/watchdog/cpu5wdt.c: "cpu5wdt: Unknown symbol
there_is_no_init_MUTEX_LOCKED_for_RT_semaphores")
