mm, swap: no need to truncate the scan border
swap_map had a static flexible size, so the last cluster won't be fully
covered, hence the allocator needs to check the scan border to avoid OOB.
But the swap table has a fixed-sized swap table for each cluster, and the
slots beyond the device size are marked as bad slots. The allocator can
simply scan all slots as usual, and any bad slots will be skipped.
