power_supply: Fix race in power_supply_uevent
Commit 54d29ad33e3483bcc7ca433a21cf294854e5154a (Power Supply: fix race in device_create) introduced a race in power_supply_uevent. Previously it checked that power_supply is available by checking for dev->driver_data. But now dev->driver_data is set before power_supply->dev is initialised.
