  When copying in and out current ICMPv6 filters on a raw IPv6 socket,
  lock the inpcb and use a local stack variable to copy to/from userspace
  so that sooptcopyin()/sooptcopyout() aren't called while holding an
  rwlock.
  
  While here, fix a bug in which a failed sooptcopyin() might lead to
  partially consistent ICMPv6 filters on the socket by not ignoring the
  error returned by sooptcopyin().
