[PATCH v1] drm/virtio: Don't create a context with default param if context_init is supported

[Dmitry Osipenko]

From: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-pra...@amd.com>

Xorg context creation fails for native contexts that use
VIRTGPU_CONTEXT_INIT because context is already initialized implicitly
when dumb buffer is created. Fix it by not creating default vrend context
if context_init is supported.
