Better I think would be to remove __func__ from those
dynamic debug pr_fmt defines.

Actually, I think it's better to never use __func__,
but that's an argument for a different day.

I think the only reason Jason did it was to always
have __func__ printed. If those become pr_debug
then anyone that really wants to can use +pf.
