net: Remove support for AIO on sockets
The only user of msg->msg_iocb was AF_ALG, but that's deprecated.
It can be removed entirely at the cost of only supporting synchronous
operations. This doesn't break userspace, which will silently block
(for a bounded amount of time) in io_submit instead of operating
asynchronously.
This also makes struct msghdr smaller, helping every other caller of
sendmsg().
