mfd: stmfx: Nullify stmfx->vdd in case of error
[ Upstream commit7c81582c0b
] Nullify stmfx->vdd in case devm_regulator_get_optional() returns an error. And simplify code by returning an error only if return code is not -ENODEV, which means there is no vdd regulator and it is not an issue. Fixes:d75846ed08
