NAK.  pci_zalloc_consistent is just as deprecated as
pci_alloc_consistent, and if you look at the implementation you'll
see that we actual zero the memory for both of them.

If you want to do some DMA-related busy work please just bulk convert
drivers from the PCI DMA API to the proper generic DMA API.  Bonus
points for automatіng that using a cocchinelle script.
