similar to: [PATCH v5] drm/virtio: Add option to disable KMS support

From: Rob Clark <robdclark at chromium.org> Add a build option to disable modesetting support. This is useful in cases where the guest only needs to use the GPU in a headless mode, or (such as in the CrOS usage) window surfaces are proxied to a host compositor.

Some minor comments below. I had to fix dri-devel mailing list

If the virtio device supports indirect ring descriptors we need only one ring entry for the whole command. Take that into account when checking whenever the virtqueue has enough free entries for our command.
