mm: khugepaged: recalculate min_free_kbytes after stopping khugepaged
When initializing transparent huge pages, min_free_kbytes would be
calculated according to what khugepaged expected.
So when transparent huge pages get disabled, min_free_kbytes should be
recalculated instead of the higher value set by khugepaged.
