ensure that ossl_obj_nid_lock is allocated before use
external calls to OBJ_new_nid will fail on an attempt to lock the
ossl_obj_nid_lock as it won't have been initalized yet.
Bifurcate OBJ_new_nid into an external and internal variant, in which
the former calls ossl_obj_write_lock (ensuring that the nid_lock is
initalized), while OBJ_create (the sole internal caller) uses the latter
to avoid having to drop and re-acquire the lock
