KVM: selftests: Add atoi_positive() and atoi_non_negative() for input validation
Many KVM selftests take command line arguments which are supposed to be
positive (>0) or non-negative (>=0). Some tests do these validation and
some missed adding the check.
Add atoi_positive() and atoi_non_negative() to validate inputs in
selftests before proceeding to use those values.
