tools/mm/page_owner_sort: return explicit filter results

Patch series "tools/mm/page_owner_sort: fix filtering and cleanup issues",
v5.

Patch 1 renames is_need() to filter_record() and makes the filter path
return explicit results.  Patch 2 fixes the per-record allocation leaks. 
Patch 3 bounds search_pattern() output copies, addressing the pre-existing
issue reported by Sashiko/AI review.


This patch (of 3):

Rename is_need() to filter_record() and make the filter path return
explicit error, skip, and match results.  This lets callers distinguish
allocation failures from records that simply do not match active filters.
