power: supply: cpcap-charger: Fix power_supply_put on null battery pointer
[ Upstream commit 39196cfe10dd2b46ee28b44abbc0db4f4cb7822f ]
Currently if the pointer battery is null there is a null pointer
dereference on the call to power_supply_put. Fix this by only
performing the put if battery is not null.
Addresses-Coverity: ("Dereference after null check")
Fixes: 4bff91bb3231 ("power: supply: cpcap-charger: Fix missing power_supply_put()")
