Fix a potential NULL pointer dereference in _init_thread().
The first NULL pointer check against `attr' suggests that `attr' can
be NULL. Then later `attr' is directly dereferenced, suggesting the
opposite.
if (attr == NULL) {
...
} else {
...
}
...
if (attr->stack_base == ...) { ... }
The public API pthread_create(3) allows NULL, and interprets it as "default".
Our implementation actually swaps in a pointer to the global default
pthread_attr_t, so we don't need any NULL checks in _init_thread. (The other
internal caller passes its own pthread_attr_t.)
