udf: Preserve link count of system files

commit fc8033a34a3ca7d23353e645e6dde5d364ac5f12 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.
