fix temp white list update in device idle

It appears firewall rules for temp white list is updated differently
from the non temp one. The non temp one will trigger a global update
but the temp one is updating only the uids in the list one by one.
The individual uid firewall rule update does not work well with dozable
chain. This cl moves the dozable chain update logic out and put it where
the white list is updated.
