Fix WAL-logging of setting the visibility map bit.
The operation that removes the remaining dead tuples from the page must
be WAL-logged before the setting of the VM bit. Otherwise, if you replay
the WAL to between those two records, you end up with the VM bit set, but
the dead tuples are still there.
Backpatch to 9.3, where this bug was introduced.
