cluster/afr: save the xattr obtained in the {f}xattrop_cbk in local
If the {f}xattrop operation succeeds on one of the subvolumes and fails on another (thus the xattr dict obtained from the failed subvolume in the callback will be NULL), then afr would be unwinding with op_ret = 0 (since the operation was successful on one subvolume), but the xattr dict would be NULL (afr is not saving the xattr it has received in the callback in its local structure and will send the xattr it has received in the last callback). xlators above afr might segfault when they access the xattr since they would have assumed that xattr would be present as op_ret is 0.
