io_uring/net: use the correct msghdr union member in io_sendmsg_copy_hdr
Rather than assign the user pointer to msghdr->msg_control, assign it
to msghdr->msg_control_user to make sparse happy. They are in a union
so the end result is the same, but let's avoid new sparse warnings and
squash this one.
