mm: smaps*: extend smap_gather_stats to support specified beginning

Extend smap_gather_stats to support indicated beginning address at which
it should start gathering.  To achieve the goal, we add a new parameter
@start assigned by the caller and try to refactor it for simplicity.

If @start is 0, it will use the range of @vma for gathering.
