power: supply: max17042_battery: Propagate status register errors

Browse source

The driver ignores errors from the initial STATUS read and final POR clear.
A failed read can leave the POR decision based on an invalid value, while a
failed clear can report initialization complete with POR still set.

Check the probe-time read and return the POR-clear result from
max17042_init_chip(). Keep this error handling separate from the retry
policy added later.
