cluster/dht: use GFID returned from hashed subvolume
.. to perform lookups on remaining subvolumes. This way, if there is a
race between two clients to 'fix' GFIDs with gfid-req, then the hashed
subvolume will arbitrate and return the winner in stbuf->ia_gfid. This
patch uses the returned gfid as the new gfid-req thereby preventing
mismatching GFIDs on other servers due to further races.
