cluster/afr: Club missing entry, missing gfid self-heals
Problem: gfid-self-heal always assigns the gfid(GFID-1) it gets from lookup. Between the time of lookup to triggering the gfid-self-heal the entry could have changed. Now lets say there is a case where one of the files of the replica subolumes already has a gfid (GFID-2) and the other does not. In that case healing should happen with GFID-2 instead of GFID-1. Fix: Missing-entry-self-heal already handles all these cases. So removed separate handling of gfid-self-heal.
