MFC r270348:
Add some missing checks for unsupported interfaces (e.g. pflog(4)) when handling ioctls. While here, remove duplicated checks for a NULL ifp in in6_control(): this check is already done near the beginning of the function. MFC r270349: Suppress warnings when retrieving protocol stats from interfaces that don't support IPv6 (e.g. pflog(4)). PR: 189117 Approved by: re (gjb)
