virtio: console: Make resize control event handling compliant with spec

According to section 5.3.6.2 of the virtio spec a control buffer with
the event VIRITO_CONSOLE_RESIZE is followed by a virtio_console_resize
struct containing 2 little endian 16bit integerts cols,rows. The kernel
implementation assums native endianness (which results in mangled values
on big endian architectures)(a seperate patch by Halil Pasic will deal with
that issue) and swaps the ordering of columns and rows.
This patch changes the ordering of rows and columns to columns then
rows.
