Introduce _prop_rwlock_tryrdlock() and use it in these functions, so
that the rwlock is *always* acquired once, while here add some
_PROP_RWLOCK_OWNED asserts to verify.
This definitely fixes the "locking against myself" panics.

Introduce _PROP_RWLOCK_OWNED() which is a KASSERT(rw_lock_held(lock))

places where it is required now.
This fixes a LOCKDEBUG panic "locking against myself", as reported by
Geoff C. Wing in current-users@.
