bpf: Print a warning only if writing to unprivileged_bpf_disabled.
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!
However, this message is only meaningful when the feature is
disabled or enabled.
