KVM: selftests: Always clear dirty bitmap after iteration

Browse source 
We used not to clear the dirty bitmap before because KVM_GET_DIRTY_LOG
would overwrite it the next time it copies the dirty log onto it.
In the upcoming dirty ring tests we'll start to fetch dirty pages from
a ring buffer, so no one is going to clear the dirty bitmap for us.
