While testing the rutabaga gpu device, we noticed that if the device is
reset, it stops working and complains about missing resource ids. A
quick investigation discovered that the generic VirtIOGPU implementation
frees all resources, but for Rutabaga, they are tied with rutabaga
objects that need to be destroyed as well.

This series adds a resource_destroy class method that the Rutabaga
device can override and do its own bookkeeping.

v1 -> v2 differences:
- addressed review comments re: using the Error API for the
  resource_destroy method.

Manos Pitsidianakis (3):
  hw/display/virtio-gpu.c: use reset_bh class method
  virtio-gpu.c: add resource_destroy class method
  virtio-gpu-rutabaga.c: override resource_destroy method
