Only print the warning message if you are writing to "/proc/sys/kernel/unprivileged_bpf_disabled". The kernel may print an annoying warning when you read "/proc/sys/kernel/unprivileged_bpf_disabled" saying WARNING: Unprivileged eBPF is enabled with eIBRS on, data leaks possible via Spectre v2 BHB attacks!
