    cluster/afr: Fix witness counting code in src/sink detection
    
    Problem:
    In afr-v1 pre-op, xattrop increments self xattr first then it increments the
    value on rest. In post-op, xattr value is decreased first on rest and at last
    it gets decremented on self. So for a possible operation to be witnessed i.e.
    a fop is seen by the brick it is important to have at least 1 pending op
    because without completing pre-op fop won't come. The other possibility is when
    fop completes but at the time of post-op after decrementing pending counts on
    others just before decrementing its own pending count, the brick dies.
    
    Fix:
    Fix witness detection code in afr_self_heal_find_direction()
