afr: Heal the directories and assign gfids when doing named lookup
If there are directories present on only one brick without having gfid (created from backend), heal them and assign gfids when named lookup comes on those directories. Change-Id: I32c27f0b04c8eb36b25899ca9fbe7aef141f13b9 Signed-off-by: karthik-us <ksubrahm@redhat.com>
