virtio_console: fix order of fields cols and rows

Browse source

commit 5326ab737a upstream.

According to section 5.3.6.2 (Multiport Device Operation) of the virtio
spec(version 1.2) a control buffer with the event VIRTIO_CONSOLE_RESIZE
is followed by a virtio_console_resize struct containing cols then rows.
The kernel implements this the wrong way around (rows then cols) resulting
in the two values being swapped.
