mds: xlock versionlock on rename if witnesses

This ensures that we don't pipeline dentry linkage updates when there
are witnesses.  That can cause problems because replicas don't see
projected dentry linkage info, and will get confused when they look at
the replica of the srcdn and it's, say, NULL and not srci.
