Under certain conditions, e.g. in a KVM guest, a write operation to /sys/firmware/cpi/set can result in an error message to stderr while the script returns with a zero exit code, indicating success. This can cause confusion if cpictl is called by systemd due to the existence of a writable /sys/firmware/cpi/. Let's silence cpictl when writing to the /sys/firmware/cpi/set. This is OK, as nothing can be inferred from failure or success from the perspective of the invoking Linux instance.
