Currently, there is a dedicated thread for following remote ns operations: - grabbing the ifindex of the interface moved to remote netns - removing xdp prog from that interface With bpf_link usage in place, this can be simply omitted, so remove mentioned thread, as BPF resources will be managed by bpf_link itself, so there's no further need for creating the thread that will switch to remote netns and do the cleanup. Keep most of the logic for switching the ns, though, but make switch_namespace() return the fd so that it will be possible to close it at the process termination time. Get rid of logic around making sure that it's possible to switch ns in validate_interfaces().
