of_property_count_u32_elems() might return an error code in some cases.
It's naturally better to assign what it's returned to the err variable
and supply the real code to the upper layer(s). Besides that, it's a
common practice to avoid assignments for the data in cases when we know
that the error condition happened. Refactor the code accordingly.
