pgsql: Update comment atop of ReorderBufferQueueMessage().

Update comment atop of ReorderBufferQueueMessage().

The comments atop of this function describes behaviour in case of a
transactional WAL message only, but it accepts both transactional and
non-transactional WAL messages. Update the comments to describe
behaviour in case of non-transactional WAL message as well.
