[ Upstream commit 3a20c444cd123e820e10ae22eeaf00e189315aa1 ]
In addition to can_dropped_invalid_skb(), the helper function can_dev_dropped_skb() checks whether the device is in listen-only mode and discards the skb accordingly.
Replace can_dropped_invalid_skb() by can_dev_dropped_skb() to also drop skbs in for listen-only mode.
