Subject: [PATCH 20/20] KVM: selftests: Allow running a single iteration of dirty_log_test

Now that dirty_log_test doesn't require running multiple iterations to
verify dirty pages, and actually runs the requested number of iterations,
drop the requirement that the test run at least "3" (which was really "2"
at the time the test was written) iterations.

Opportunistically use atoi_positive() to do the heavy lifting.
