mds: mds returns -5 error when the deleted file does not exist

For files that do not exist, we should set it to -ESTALE instead of -EIO,
because this error code will be returned to the NFS client and transparently
passed to the application layer. The application layer may handle -EIO and
-ESTALE differently. And lead to misjudgment
