Partially roll back overenthusiastic SSI optimization. When a regular lock is held, SSI can use that in lieu of a predicate lock to detect rw conflicts; but if the regular lock is being taken by a subtransaction, we can't assume that it'll commit, so releasing the parent transaction's lock in that case is a no-no.
