leds: trigger: netdev: 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 warnings:
./drivers/leds/trigger/ledtrig-netdev.c:291:3-10: WARNING: NULL check before dev_{put, hold} functions is not needed.
./drivers/leds/trigger/ledtrig-netdev.c:401:2-9: WARNING: NULL check before dev_{put, hold} functions is not needed.
