ck_rwlock: Fix behavior for weakly-ordered systems.
...
As ck_pr semantics were still not molded, I was designing
under the assumption I would potentially go towards
acq/req interface. Since RMO will be the semantic norm for
the ck_pr model from now on, enforce stricter ordering
requirements on rwlock.
ck_rwlock_write_unlock function will now also serialize both
loads and stores.
