[roll] Roll fuchsia [kernel][vm] Avoid excessive scanning Changes the way the access_scan_period is calculated and used to avoid redundant scans. The intention of the regular access scanner is that there is at most access_scan_period between scans, but the existing implementation had a scenario where if did a routine scan at time A, and then waited till time A+period, if a scan from the page queues were to happen just moments before (i.e. A+period-delta) then we would still rescan. This change corrects this issue and ensures that the periodic scan only occurs if nothing else triggered a scan for at least the period.
