    afr : Enable auto heal when replica count increases

    This patch is part two change to prevent data loss
    in a replicate volume on doing a add-brick operation.

    Problem: After doing add-brick, there is a chance
    that self heal might happen from the newly added
    brick rather than the source brick, leading to data loss.

    Solution: Mark pending changelogs on afr children for
    the new afr-child so that heal is performed in the
    correct direction.
