I think it's better to use as labels what will be done in the error path
rather than what failed. IOW, "disable_axius_clk" or "disable_clks" are
more clear than vdd33_err for me, since can give you an idea of what will
happen in the error path.

But I don't have a strong opinion and your naming is an improvement over
the current one, so:
