heal: fix the way we check the presence of AFR in glfsheal

Problem:
glfsh_validate_replicate_volume() used to check if AFR was the parent of
all client xlators present in the graph. This need not always be true, for
example, for user-serviceable-snapshots where the parent of snapd-client is
snapview-client.

Fix:
glfsh_validate_replicate_volume() returns true if atleast one client
xlator has AFR as its parent. Also, AFR need not be its immediate
parent, but be present somewhere in its parent ancestry.
