The device topology on the restore node can be different from the
topology on the checkpointed node. The GPUs on the restore node may
have different gpu_ids, minor number. or some GPUs may have different
properties as checkpointed node. During restore, the CRIU plugin
determines the target GPUs to avoid restore failures caused by trying
to restore a process on a gpu that is different.

Parse local system topology in /sys/class/kfd/kfd/topology/nodes/ and
store properties for each gpu in the CRIU image files. The gpu
properties can then be used later during restore to make the process is
restored on gpu's with similar properties.
