[ Upstream commit a1e654070a60d5d4f7cce59c38f4ca790bb79121 ]
netif_rx() is meant to be called from interrupt contexts. can_restart() may be
called by can_restart_work(), which is called from a worqueue, so it may run in
process context. Use netif_rx_ni() instead.
Fixes: 39549eef3587 ("can: CAN Network device driver and Netlink interface")
