cluster/afr: Fix mem-leak

Browse Source 
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
