percpu: use chunk scan_hint to skip some scanning Just like blocks, chunks now maintain a scan_hint. This can be used to skip some scanning by promoting the scan_hint to be the contig_hint. The chunk's scan_hint is primarily updated on the backside and relies on full scanning when a block becomes free or the free region spans across blocks.
