Do not clear need_mi_flush within the batch. 

This is a situation that should not be possible, need_mi_flush being
true but the list of pending flush pixmaps being clear. However, an
earlier bug in doing just that revealed this minor bug. So for
correctness, be careful not to clear need_mi_flush without emitting a
MI_FLUSH.
