power: supply: fix residue sysfs file in error handle route of __power_supply_register()

If device_add() succeeds, we should call device_del() when want to
get rid of it, so move it into proper jump symbol.

Otherwise, when __power_supply_register() returns fail and goto
wakeup_init_failed to exit, there is still residue device file in sysfs.
When attempt to probe device again, sysfs would complain as below:

sysfs: cannot create duplicate filename '/devices/platform/i2c/i2c-0/0-001c/power_supply/adp5061'
