Three small cleanups for mm/damon/core.c:

1. Extract duplicated scheme-index-finding loops into a helper.

2. Use the already-maintained damon_nr_regions() instead of walking the
   region list to count in damon_commit_target_regions().

3. Move the static last_nr_regions variable in kdamond_split_regions()
   into struct damon_ctx so each kdamond tracks its own state.

  mm/damon/core: deduplicate scheme index lookup into helper
  mm/damon/core: use damon_nr_regions() in damon_commit_target_regions()
  mm/damon/core: move last_nr_regions from static local to damon_ctx
