power: generic-adc-battery: return meaningful error when no channel available

Commit-Message
From: Heiko Stuebner <heiko.stuebner@...> When no channel was found the driver currently always returns -ENODEV. This hides the actual error which is available in ret from the kernel and disables for example -EPROBE_DEFER handling. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
