6.12-stable review patch. If anyone has any objections, please let me know.

From: Marc Kleine-Budde mkl@pengutronix.de
[ Upstream commit 0bee15a5caf36fe513fdeee07fd4f0331e61c064 ]
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.
