ipv6: set msg_control_is_user in do_ipv6_getsockopt

While do_ipv6_getsockopt does not call the high-level recvmsg helper,
the msghdr eventually ends up being passed to put_cmsg anyway, and thus
needs msg_control_is_user set to the proper value.

Fixes: 1f466e1f15cf ("net: cleanly handle kernel vs user buffers for ->msg_control")
