power_supply: Fix race in power_supply_uevent

Browse Source 
Commit 54d29ad33e (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.
