mutex: remove mutex trylock holder check

Browse Source 
The standard describes trylock as follows, trylock should never cause the system to stop running:

The pthread_mutex_trylock() function shall be equivalent to
pthread_mutex_lock(), except that if the mutex object referenced by
mutex is currently locked (by any thread, including the current thread),
the call shall return immediately.
