KVM: selftests: Add atoi_paranoid() to catch errors missed by atoi()

Browse source 
atoi() doesn't detect errors. There is no way to know that a 0 return
is correct conversion or due to an error.

Introduce atoi_paranoid() to detect errors and provide correct
conversion. Replace all atoi() calls with atoi_paranoid().
