power: supply: cpcap-battery: Fix division by zero
[ Upstream commit dbe7208c6c4aec083571f2ec742870a0d0edbea3 ]
If called fast enough so samples do not increment, we can get
division by zero in kernel:
__div0
cpcap_battery_cc_raw_div
cpcap_battery_get_property
power_supply_get_property.part.1
power_supply_get_property
power_supply_show_property
power_supply_uevent
