[PATCH] drm/virtio: Don't detach GEM from a non-created context

[Jason Macnak]

Applies the same treatment as commit 7cf6dd467e87 ("drm/virtio:
Don't attach GEM to a non-created context in gem_object_open()")
to virtio_gpu_gem_object_close() to avoid trying to detach
a resource that was never attached due to a context
never being created when context_init is supported.

Fixes: 086b9f27f0ab ("drm/virtio: Don't create a context with default param if 
context_init is supported")
