[PATCH 28/29] can: j1939: fix memory leak if filters was set

[Marc Kleine-Budde]

From: Oleksij Rempel <o.rem...@pengutronix.de>

Filters array is coped from user space and linked to the j1939 socket.
On socket release this memory was not freed.

Fixes: 9d71dd0c7009 ("can: add support of SAE J1939 protocol")
