New definition.
* sysdeps/generic/pt-mutexattr.c (__pthread_recursive_mutexattr):
New declaration.
* sysdeps/generic/pt-mutex-init.c (_pthread_mutex_init): If ATTR
is &__PTHREAD_RECURSIVE_MUTEXATTR, don't allocate a copy, just
save in MUTEX->ATTR.

MUTEX->ATTR is &__PTHREAD_RECURSIVE_MUTEXATTR, don't free it.
