[PATCH 2/3] tools/power/x86/intel-speed-select: Print Version info when Incompatible API version is detected

[Zhang Rui <rui.zhang@intel.com>]

When running an old version intel-speed-select tool on newer platforms,
even with "intel-speed-select -v", the tool only complains about
"Incompatible API version", without giving the current version info.

Print Version info whenever Incompatible API version is detected.
