When resetting we don't want to *reset* the dirty bitmap,
we want to *set* it to mark the entire VRAM dirty due to
the memset() call.
Replace memory_region_reset_dirty() by tcx_set_dirty()
which conveniently set the correct ranges dirty.

I don't think the size calculation of MAXX * MAXY is correct when comparing with
above? I think it's easiest just to use the same approach as update_palette_entries()
here e.g.
tcx_set_dirty(s, 0, memory_region_size(&s->vram_mem));
