Between the initial and final versions of the function setup_hw_stats,
the order of variable initialization was changed. However, the unwind
flow on error did not properly keep up with the flow changes. Make
the unwind flow match a proper unwind of the allocation flow, then
remove no longer needed variable initializations.
