Jeffy Chen 0ddaa7d9eb virtual_battery: Avoid unexpected batt_mode_cache refreshing ...

Currently we are assuming batt_mode would never be zero, but that is not
always true. Some battery do report zero for batt_mode(bob for example).

So everytime the batt_mode_cache been set to zero, the virtual_battery
would consider it uninited, and tries to refresh the next time.

Use -1 as uninited batt_mode_cache to avoid that.

BUG=b:66555246
BRANCH=gru
TEST=Check on bob, the battery level is correct.
