can: raw: Remove NULL check before dev_{put, hold}

Browse Source 
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.
