For rwlock_destroy() this can be done, although I would be very careful with
introducing such change.  mutex_destroy() EINVAL caused too many grief.

For cv_desstroy(), I do not see a good way to actually implement it.  We have
user/kernel sleeping threads, and although for user sleep this can be
implemented with the same races as for mutex_destroy(), for kernel it seems to
require new umtx op to cover just this case.  I do not see it worth.
