[PATCH 3/3] tools/power/x86/intel-speed-select: Fix output when running on unsupported CLX platforms

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

When running intel-speed-select on unsupported CLX platforms, it prints
 intel-speed-select: Invalid CPU model (85)
 : Success
Because this is not a system error and errno is not set.

Replace err() with exit().
