can: raw: Remove NULL check before dev_{put, hold}
The call netdev_{put, hold} of dev_{put, hold} will check NULL, so there is no need to check before using dev_{put, hold}, remove it to silence the warning: ./net/can/raw.c:497:2-9: WARNING: NULL check before dev_{put, hold} functions is not needed.
