Rework MOUNTED/DOING SOFTDEP/SUJ macros

Browse Source 
Now MNT_SOFTDEP indicates that SU are active in any variant +-J, and
SU+J is indicated by MNT_SOFTDEP | MNT_SUJ combination.  The reason is
that unmount will be able to easily hide SU from other operations by
clearing MNT_SOFTDEP while keeping the record of the active journal.
