libc/pthread: Return EINVAL when input parameter incorrect at pthread_once

https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_once.html

If an implementation detects that the value specified by the once_control
argument to pthread_once() does not refer to a pthread_once_t object
initialized by PTHREAD_ONCE_INIT, it is recommended that the function
should fail and report an [EINVAL] error.
