Linus Lüssing 5f8156fd34 batman-adv: Fix multicast packet loss with a single WANT_ALL_IPV4/6 flag 
[ Upstream commit 74c12c630f ]

As the kernel doc describes too the code is supposed to skip adding
multicast TT entries if both the WANT_ALL_IPV4 and WANT_ALL_IPV6 flags
are present.

Unfortunately, the current code even skips adding multicast TT entries
if only either the WANT_ALL_IPV4 or WANT_ALL_IPV6 is present.

This could lead to IPv6 multicast packet loss if only an IGMP but not an
MLD querier is present for instance or vice versa.

Fixes: 687937ab34 ("batman-adv: Add multicast optimization support for bridged setups")
