cluster/afr: Fix mem-leak
Backport of http://review.gluster.org/8457
Problem:
local->xattr_req is already reffed with xattr_req that comes
in lookup fop. But when afr_lookup_xattr_req_prepare is called
local->xattr_req is over-written with dict_new() which leads
to ref leak on the dict which came in lookup fop
Fix:
Create local->xattr_req only when it is NULL
BUG: 1128801
