Toke Høiland-Jørgensen 23ab656be2 libbpf: Prevent overriding errno when logging errors 
Turns out there were a few more instances where libbpf didn't save the
errno before writing an error message, causing errno to be overridden by
the printf() return and the error disappearing if logging is enabled.
