ec/lenovo/h8: Guard against EC bugs in the battery status logic.
On my Thinkpad with an H8-compatible ENE KB9012 EC (GDHT92WW 1.52), when
the battery is nearly full and we switch from battery to AC by plugging
in the cable, the current rate will not drop to 0 immediately, but the
discharging state is cleared immediately.
This leads to the code trying to process an invalid rate value >0x8000,
leading to a displayed rate of >1000W.
This patch changes the logic to deal with these corner cases.
