similar to: [PATCH] Revert "virtio_console: Initialize guest_connected=true for rproc_serial"

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> When rproc_serial is initialized, guest_connected should be set to true. We can then revert the extra checks introduced in commit: "virtio_console: Let unconnected rproc device receive data."

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> Allow rproc serial ports to receive data before the port is connected. Rproc serial ports usually talk to very simple remote devices with no control queue managing open/close events. So we must let remote devices write to the virtio ring even if the device is not yet fully initialized. Signed-off-by: Sjur Br?ndeland

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> I thought rebasing rproc_serial to linux-next was going to be trivial. But when starting the merge I realized that I had to refactor the the patches from Masami Hiramatsu. The splice support has the same issue as I faced, with different type of buffers in the out_vq. So I ended up refactoring the splice functionality. The code size
