If we migrate when the device is not in a native state the guest still believes the slots are created, and will cause operations that reference the slots, causing a "panic: virtual address out of range" on the first of them. Easy to see by migrating in vga mode (with a driver loaded, for instance windows cmd window in full screen mode) and then exiting vga mode back to native mode will cause said panic. Fixed by doing the slot recreation unconditionally at post_load
Added to spice patch queue. thanks, Gerd
