[PATCH] can: rockchip: bail out if skb cannot be allocated

[Chenyuan Yang]

Add NULL pointer check in rkcanfd_handle_error_int() to
bail out if skb cannot be allocated.

This is similar to the commit f7f0adfe64de
("can: rockchip: rkcanfd_handle_rx_fifo_overflow_int(): bail out if skb cannot be allocated").
