afr: launch index heal on local subvols up on a child-up event

Backport of http://review.gluster.org/#/c/11912/
Problem:
When a replica's child goes down and comes up, the index heal is
triggered only on the child that just came up. This does not serve the
intended purpose as the list of files that need to be healed
to this child is actually captured on the other child of the replica.

Fix:
Launch index-heal on all local children of the replica xlator which just
received a child up. Note that afr_selfheal_childup() eventually calls
afr_shd_index_healer() which will not run the heal on non-local
children.
