  Merge r180968 from head to stable/7:
  
    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().
