net: add receive_disabled logic to iov delivery path
This patch adds the missing NetClient->receive_disabled logic in the sendv delivery code path. It seems that commit 893379efd0e1b84ceb0c42a713293f3dbd27b1bd ("net: disable receiving if client returns zero") only added the logic to qemu_deliver_packet() and not qemu_deliver_packet_iov(). The receive_disabled flag should be automatically set when .receive(), .receive_raw(), or .receive_iov() return 0. No further packets will be delivered to the NetClient until the receive_disabled flag is cleared again by calling qemu_flush_queued_packets(). Typically the NetClient will wait until its file descriptor becomes writable and then invoke qemu_flush_queued_packets() to resume transmission.
