iov: handle partial writes from sendmsg and recvmsg

Partial writes can still happen in sendmsg and recvmsg, if a
signal is received in the middle of a write. To handle this,
retry the operation with a new offset/bytes pair.

iov: reorganize iov_send_recv, part 1

Once the initial part of the iov is dropped, it is not used anymore.

iov: reorganize iov_send_recv, part 2

Do not touch the "bytes" argument anymore. Instead, remember the

qemu/iovec: Don't assert if sbytes is zero

Since these values can possibly be sent from guest (for hw/9pfs), do a sanity check
on them. A 9p write request with 0 bytes caused qemu to abort without this patch
