can: rockchip-canfd: rkcanfd_start_xmit(): use can_dev_dropped_skb() instead of can_dropped_invalid_skb()

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.
