Subject: [PATCH 18/21] drm/virtio: make virtio_gpu_debugfs() return void.

Since 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), drm_debugfs_create_files()
never fails and should return void. Therefore, remove its use as the
return value of virtio_gpu_debugfs() and have the latter function return
void.
