AFAICT, pci_p2pmem_dma() *never* existed.  I suppose it was a typo,
and pci_p2pdma_distance_many() was intended?

I'm happy to either merge this patch (with an updated commit log) to
remove the comment text or merge a patch correct the comment text.

I just don't want to merge this with a commit log that says we removed
the pci_p2pmem_dma() method when it never actually existed.
