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.
