[PATCH 2/2] power: supply: core: simplify power_supply_class_init

[Sebastian Reichel]

Technically the sysfs attributes should be initialized
before the class is registered, since that will use them.
As a nice side effect this nicely simplifies the code,
since it allows dropping the helper variable.
