           Summary: gfid-reset of a directory in distributed replicate
                    volume doesn't set gfid on 2nd till last subvolumes
           Product: GlusterFS
           Version: 3.7.9
         Component: replicate

+++ This bug was initially created as a clone of Bug #1312816 +++

Description of 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.

    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
