samus: fix false shutdown due to low battery
Fix bug causing unit to falsely shutdown due to low battery.
The shutdown warning time was not getting reset, so two false
readings of battery SOC or voltage, seperated by more than 30
seconds in time would cause "charge force shutdown due to low
battery"
BUG=chrome-os-partner:33111, chrome-os-partner:33144

TEST=make buildall
