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: Brick-logs: [2016-11-08 07:41:49.387127] W [MSGID: 115009] [server-resolve.c:566:server_resolve] 0-rep-server: no resolution type for (null) (LOOKUP) [2016-11-08 07:41:49.387157] E [MSGID: 115050] [server-rpc-fops.c:156:server_lookup_cbk] 0-rep-server: 91833: LOOKUP(null) (00000000-0000-0000-0000-000000000000/16d47463-ece5-4b33-9c93-470be918c0f6.82) ==> (Invalid argument) [Invalid argument] Client-logs: [2016-11-08 07:41:27.497687] W [MSGID: 114031] [client-rpc-fops.c:2930:client3_3_lookup_cbk] 2-rep-client-0: remote operation failed.
