Stop relying on the submit BO list, which won't exist with the new
"VM_BIND" uAPI. Instead, create a separate list in generic code, only
when dumping is enabled. As a bonus this means that it should work on
virtio and kgsl too, and more code is removed from the kernel backend.
We need to use the generic fence wait introduced in the previous commit.
