This reverts commit 97807e75956a2d240282bc64fab1b71762de0546.
In a distribute or distribute-replica volume, this fix is required to prevent
gfid mis-match due to race issues.
test script bug-767585-gfid.t needs a sleep of 2, cause after setting backend
gfid directly, we try to heal, and with this fix, we do not allow setxattr of
gfid within creation of 1 second if not created by itself

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.
