cluster/afr: Don't delete gfid-req from lookup request
Problem:
Afr does dict_ref of the xattr_req that comes to it and deletes "gfid-req" key.
Dht uses same dict to send lookup to other subvolumes. So in case of
directories and more than 1 dht subvolumes, second subvolume till the last
subvolume won't get a lookup request with "gfid-req". So gfid reset never
happens on the directories in distributed replicate subvolume for 2nd till last
subvolumes.
Fix:
Make a copy of lookup xattr request.
Also fixed replies_wipe possibly resetting gfid to NULL gfid
BUG: 1312816
