RAID: Report RAID images split with tracking as out-of-sync ("I").

Browse Source 
Split image should have an out-of-sync attr ('I') - always.  Even if
the RAID LV has not been written to since the LV was split off, it is
still not part of the group that makes up the RAID and is therefore
"out-of-sync".
