virtio-gpu: maintain command queue

Browse source 
We'll go take out the commands we receive out of the virt queue and put
them into a linked list, to decouple virtio queue handling from actual
command processing.

Also move cmd processing to new virtio_gpu_handle_ctrl func, so we can
easily kick it from different places.
