tools/power/x86/intel-speed-select: Fix some program return value

When running the "intel-speed-select -h" command, it returns
1. 0 when using a version that is API incompatible.
2. 1 when using a version that is API compatible.
And this is confusing.

Fix the program to return 0 for "-h" parameter, and return 1 whenever
"Incompatible API versions" is detected.
