In the case of VFIO, the unrealize callback is too early to munmap the BARs. The munmap must be delayed until memory accesses are complete. To do this, split vfio_unmap_bars in two. The removal step, now called vfio_unregister_bars, remains in vfio_exitfn. The reclamation step is vfio_unmap_bars and is moved to the instance_finalize callback. Similarly, quirk MemoryRegions have to be removed during vfio_unregister_bars, but freeing the data structure must be delayed to vfio_unmap_bars.
