__mutex_owner() should only be used by the mutex api's. So, to put this restiction let's move the __mutex_owner() function definition from linux/mutex.h to mutex.c file. There exist functions that uses __mutex_owner() like mutex_is_locked() and mutex_trylock_recursive(), So to keep legacy thing intact move them as well and export them. Move mutex_waiter structure also to keep it private to the file.
