libglusterfs/graph: pass correct translator pairs during reconfigure
when we autoload xlators like acl, worm or mac-compatibility,
they will be loaded on top of old graph.
However, corresponding ones won't be present in new graph, since
newgraph doesn't contain autoloaded translators. While
passing xlator pairs to reconfigure, this fact should be accounted
and correct xlator pairs should be passed instead of blindly passing
oldgraph->first and newgraph->first.
