can: ctucanfd: handle skb allocation failure
If skb allocation fails, the pointer to struct can_frame is NULL. This
is actually handled everywhere inside ctucan_err_interrupt() except for
the only place.
Add the missed NULL check.
Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.
