drm/virtio: Allow importing prime buffers when 3D is enabled
This functionality was added for using a KMS-only virtgpu with a physical
(or SR-IOV) headless GPU in passthrough, but it should not be restricted
to KMS-only mode. It can be used with cross-domain to pass guest memfds
to the host compositor with zero copies (using udmabuf on both sides).
Drop the check for the absence of virgl_3d to allow for more use cases.
Fixes: ca77f27a2665 ("drm/virtio: Import prime buffers from other devices as guest blobs")
