bufmgr: Remove the, now obsolete, BM_JUST_DIRTIED
Due to the recent changes to use a share-exclusive mode for setting hint bits
and for flushing pages - instead of using share mode as before - a buffer
cannot be dirtied while the flush is ongoing. The reason we needed
JUST_DIRTIED was to handle the case where the buffer was dirtied while IO was
ongoing - which is not possible anymore.
