tcp: Get rid of iov with cached MSS, drop sendmmsg(), add deferred flush
Caching iov_len for messages from socket doesn't actually decrease
overhead by the tiniest bit, and added a lot of complexity. Drop
that.
Also drop the sendmmsg(), we don't need to send multiple messages
with TCP, as long as we make sure no messages with a length
descriptor are sent partially, qemu is fine with it.
Just like it's done for segments without data (flags), also defer
the sendmsg() for sending data segments, to improve batching.
