rtmutex_api: provide correct extern functions
Commit fb49f07ba1d9 ("locking/mutex: implement mutex_lock_killable_nest_lock")
changed the set of functions that mutex.c defines when CONFIG_DEBUG_LOCK_ALLOC
is set.
- it removed the "extern" declaration of mutex_lock_killable_nested from
include/linux/mutex.h, and replaced it with a macro since it could be
treated as a special case of _mutex_lock_killable. It also removed a
definition of the function in kernel/locking/mutex.c.
- likewise, it replaced mutex_trylock() with the more generic
mutex_trylock_nest_lock() and replaced mutex_trylock() with a macro.
However, it left the old definitions in place in kernel/locking/rtmutex_api.c,
which causes failures when building with CONFIG_RT_MUTEXES=y. Bring over
the changes.
