KVM: selftests: Print the errno besides error-string in TEST_ASSERT

Browse source 
Print the errno besides error-string in TEST_ASSERT in the format of
"errno=%d - %s" will explicitly indicate that the string is an error
information. Besides, the errno is easier to be used for debugging
than the error-string.
