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

    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.
