No low battery shutdown in ACTDEAD

This fix is to prevent reboot loop in case empty battery is connected to charger.
Loop happened like this
1) Connect USB cable
2) Devices wakes up and goes to ACTDEAD
3) Dsme sees that battery level is too low and started shutdown
4) Device shutdown
5) Device wakes up because of USB connected
6) goto 2

Fix is to step 3. In actdead we don't start low battery shutdown
