[3/3] benchtests: Catch exceptions in input arguments

  From: Leonardo Sandoval <leonardo.sandoval.gonzalez@linux.intel.com>

Catch runtime exceptions in case the user provided either wrong base
function or attribute(s). In any of the latter, quit immediately with
non-zero return code.

	* benchtests/scripts/compare_string.py: (process_results) Catch
	exception in non-existent base_func.
	(process_results) Catch exception in non-existent attribute.
