kernel - SWAP CACHE part 22/many - Fix counter overflow introduced in part 21
* vm_swapcache_inactive_heuristic can overflow, making it extremely negative
and causing swapcache writing to cease for a long period of time.
* Two-in-one fix. Check if it is too negative and reset it. This also
automatically adjusts the heuristic if the sysop manually changes
the hysteresis to a smaller value.
