migration: Count new_dirty instead of real_dirty
real_dirty_pages becomes equal to total ram size after dirty log sync
in ram_init_bitmaps, the reason is that the bitmap of ramblock is
initialized to be all set, so old path counts them as "real dirty" at
beginning.
This causes wrong dirty rate and false positive throttling.
