clk: versaclock: return value calculated by ERR_PTR

In versaclock_get_name -ENOMEM is passed to ERR_PTR but nothing is
done with the value that this calculates which is obviously not the
intention of the code. This is confirmed by the code around where this
function is called.
Instead return the value from ERR_PTR.

This issue was found by Smatch.
