mm: swap: relaim the cached parts that got scanned
This commit implements reclaim during scan for cluster allocator.
Cluster scanning were unable to reuse SWAP_HAS_CACHE slots, which could
result in low allocation success rate or early OOM.
So to ensure maximum allocation success rate, integrate reclaiming with
scanning. If found a range of suitable swap slots but fragmented due to
HAS_CACHE, just try to reclaim the slots.
