dnsmasq: also suppress RA logging if DHCP logging is disabled

Asus actually defaults to quiet-ra already being set, so this is not necessary.  Revert "dnsmasq: also suppress RA logging if DHCP logging is disabled"

This reverts commit 96bcbbaeaca91e327b96dfd88c2f0e794d92a473.

minidlna: The RT-AC66U also needs to use that built-in icon.  Since we share the same device casing as the N66U, share the same icon as well
