power: supply: ab8500: Fix error handling when calling iio_read_channel_processed()

Browse source

The ab8500_charger_get_[ac|vbus]_[current|voltage]() functions should
return an error code on error.

Up to now, an un-initialized value is returned.
This makes the error handling of the callers un-reliable.

Return the error code instead, to fix the issue.
