From: "Yan, Zheng" <zheng.z.yan@xxxxxxxxx>
Server::_rename_prepare() adds null dest dentry to the EMetaBlob if
the rename operation overwrites a remote linkage. This is incorrect
because null dentry are processed after primary and remote dentries
during journal replay. The erroneous null dentry makes the dentry of
rename destination disappear.
