  Log Message:
  -----------
  Fix multicast source filter races

Copy source filter arrays before operating on socket multicast state so IP_MSFILTER and IPV6_MSFILTER do not drop the INP lock while holding pointers into mutable membership data.

This ports the FreeBSD SA-26:29 ip6_multicast fix pattern for CVE-2026-49412.
