mfd: stmfx: Nullify stmfx->vdd in case of error
[ Upstream commit 7c81582c0bccb4757186176f0ee12834597066ad ]
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.
