Markus Stockhausen d108030728 realtek: eth: validate DSA trailer length ...

Check that the skb is large enough to contain the DSA trailer before
accessing it in rteth_get_dsa_port().

Without the check, packets shorter than four bytes could result in an
out-of-bounds access when looking for the RTL Otto trailer.

Return -ENOENT when no valid DSA trailer is present.
