memory: track DIRTY_MEMORY_CODE in mr->dirty_log_mask
DIRTY_MEMORY_CODE is only needed for TCG. By adding it directly to mr->dirty_log_mask, we avoid testing for TCG everywhere a region is checked for the enabled/disabled state of dirty logging. Reviewed-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
