KVM: selftests: Read per-page value into local var when verifying dirty_log_test

Cache the page's value during verification in a local variable, re-reading
from the pointer is ugly and error prone, e.g. allows for bugs like
checking the pointer itself instead of the value.

No functional change intended.
