udf: Preserve link count of system files

commit 38a046f5cbc4b7420e2d8db17b202ba1740c8944 upstream.

System files in UDF filesystem have link count 0. To not confuse VFS we
fudge the link count to be 1 when reading such inodes however we forget
to restore the link count of 0 when writing such inodes. Fix that.
