net: bridge: allow IPv6 when multicast flood is disabled

Browse Source 
[ Upstream commit 8953de2f02ad7b15e4964c82f9afd60f128e4e98 ]

Even with multicast flooding turned off, IPv6 ND should still work so
that IPv6 connectivity is provided. Allow this by continuing to flood
multicast traffic originated by us.
