    features/shard: Fill loc.pargfid too for named lookups on individual shards

            Backport of: http://review.gluster.org/#/c/15788/

    On a sharded volume when a brick is replaced while IO is going on, named
    lookup on individual shards as part of read/write was failing with
    ENOENT on the replaced brick, and as a result AFR initiated name heal in
    lookup callback. But since pargfid was empty (which is what this patch
    attempts to fix), the resolution of the shards by protocol/server used
    to fail and the following pattern of logs was seen:

    Brick-logs:

    Also, this patch makes AFR by itself choose a non-NULL pargfid even if
    its ancestors fail to initialize all pargfid placeholders.
