For the umpteenth time, stop dumping statistics into debugfs.

Export them like any other statistic, via ethtool.

This applies to the existing debugfs you're building on top
of in this change as well, I very much regret not catching
that when it initially went in.

Please stop, in general, using debugfs as a dumping ground
for thing you can't initially figure out how to export via
normal standard interfaces.
