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

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