can: usb_8dev: usb_8dev_start_xmit(): fix double dev_kfree_skb() in error path
commit 3d3925ff6433f98992685a9679613a2cc97f3ce2 upstream.
There is no need to call dev_kfree_skb() when usb_submit_urb() fails
because can_put_echo_skb() deletes original skb and
can_free_echo_skb() deletes the cloned skb.
Fixes: 0024d8ad1639 ("can: usb_8dev: Add support for USB2CAN interface from 8 devices")
