power_supply: charger-manager: Fix dereferencing of ERR_PTR

Browse source 
If power_supply_register() fails do not dereference returned ERR_PTR.
The pointer was dereferenced to print name of battery which registration
failed. Instead use the name from the power supply description passed to
the power_supply_register() function.
