regulator: core: don't print an error when no regulator is found
Only print an error when _regulator_get() is expected to return a valid
regulator, that is when _regulator_get() is called from regulator_get() and
we're not using the dummy because we don't have full-constraints, or when
_regulator_get() is called from regulator_get_exclusive() in which case
returning a dummy is not allowed.
