mds: lock remote inode's primary dentry during rename

commit 1203cd2110 (mds: allow open_remote_ino() to open xlocked dentry)
makes Server::handle_client_rename() xlocks remote inodes' primary
dentry so witness MDS can open xlocked dentry. But I added remote inodes'
projected primary dentries to the xlock list. This is wrong because
projected dentries are invisible for path traverse.
