In es58x_rx_err_msg(), if can->do_set_mode() fails, the function
directly returns without calling netif_rx(skb). This means that the
skb previously allocated by alloc_can_err_skb() is not freed. In other
terms, this is a memory leak.

This patch simply removes the return statement in the error branch and
let the function continue.

* Appendix: how the issue was found *
Thanks for the explanation, but I think I'll remove the appendix while
applying.

Thanks,
Marc
