can: usb_8dev: usb_8dev_start_xmit(): fix double dev_kfree_skb() in error path

Browse source

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: 0024d8ad16 ("can: usb_8dev: Add support for USB2CAN interface from 8 devices")
