can: skb: drop tx skb if in listen only mode
Frames can be directly injected to a can driver via the packet
socket. By doing so, it is possible to reach the
net_device_ops::ndo_start_xmit function even if the driver is
configured in listen only mode.
Add a check in can_dropped_invalid_skb() to discard the skb if
CAN_CTRLMODE_LISTENONLY is set.
