Fix broken halt while in healthd charger mode
Reboots/halts aren't working in healthd charger mode. This is causing high power draw in an unplugged, powered off state. Steps to reproduce (on Nexus 5): Unplug device from USB charger/computer Turn device off Wait for device to turn off Plug in USB cable/charger Wait for charge animation (wait for animation, not just lightning bolt, may have to press power button briefly to get animation going) Wait for panel to turn off Unplug USB cable/charger Press power button again, notice screen turns on at some frame in the animation. (not important) Each press of the power button advances the animation Power on.
