cluster/afr: Do not increment healed_count if no healing was performed

        Backport of: http://review.gluster.org/9713

PROBLEM:
When file modifications are happening while index heal is launched,
index healer could pick up entries which appeared in indices/xattrop
transiently during the course of the operations on the mount point, and
do not really need any heal. This will cause index healer to keep doing
index-heal in a loop as long as it finds this entry, by believing that
it did successfully heal some gfids even when it didn't.

FIX:
afr_selfheal() now returns a 1 to indicate that it did not (need to)
heal a given gfid. afr_shd_selfheal() will not increment healed_count
whenever afr_selfheal() returns a 1.
