regulator: palmas: Fix palmas_probe error handling
Fix below error handling cases:
1. If reading PALMAS_SMPS_CTRL fails, simply returns ret rather than goto
err_unregister_regulator because we have not call regulator_register().
2. If palmas_ldo_init() fails, we need to call regulator_unregister() for the
regulator we just successfully registered in this for loop iteration.
