This reverts commite5de9ea779. The patch introduced `map__zput(new_node->map)` in the kcore load path, causing a segmentation fault when running `perf c2c report`. The issue arises because `maps__merge_in` directly modifies and inserts the caller's `new_map`, causing it to be freed prematurely while still referenced by kmaps. Later branchs (6.12, 6.15, 6.16) are not affected because they use a different merge approach with a lazily sorted array, which avoids modifying the original `new_map`.
