iio: devm_regulator_get_optional never returns NULL
This patch is inspired by a comment of Jonathan Cameron on patch of
Linus Walleij commit aeb55fff3891834e07a3144159a7298a19696af8 ("iio:
st_sensors: fetch and enable regulators unconditionally"). Because
changes made in this patch are actually reference generators they should
be using devm_regulator_get_optional, but if they do not explicitly set
the reference to NULL they should not be using IS_ERR_OR_NULL, but
simple IS_ERR check.
