This function is getting more to clean up in the following patches. Structuring the cleanups in one labeled block will allow reusing the same cleanup from several places.

The testsuite that checks for mcast_max_groups functionality will need to wipe the added groups as well. Add helpers to build an IGMP or MLD packets announcing that host is leaving a given group.

The testsuite that checks for mcast_max_groups functionality will need to generate IGMP and MLD packets with configurable number of (S,G) addresses. To that end, further extend igmpv3_is_in_get() and mldv2_is_in_get() to allow a list of IP addresses instead of one address.

...prevent userspace from passing garbage. Note that this patchset only touches the former policy. The latter was adjusted for completeness' sake. There do not appear to be other _deprecated calls with non-NULL policies.

Support setting the FDB limit through ip link. The arguments is: - fdb_max_learned: A 32-bit unsigned integer specifying the maximum number of learned FDB entries, with 0 disabling the limit. Also support reading back the current number of learned FDB entries in the bridge by this count. The returned value's name is: - fdb_n_learned: A 32-bit unsigned
