power: supply: sbs-battery: use dev_err_probe

Introduce usage of dev_err_probe in probe routine, which makes the code slightly more readable and removes some lines of code. It also removes PROBE_DEFER errors being logged by default, which are common when the battery is waiting for the charger driver to be registered. This also cleans up a useless goto and instead returns directly. Signed-off-by: Sebastian Reichel <[email protected]>
