Logan Gunthorpe 91fb2b6052 nvme-pci: convert to using dma_map_sgtable() ... The dma_map operations now support P2PDMA pages directly. So remove the calls to pci_p2pdma_[un]map_sg_attrs() and replace them with calls to dma_map_sgtable(). dma_map_sgtable() returns more complete error codes than dma_map_sg() and allows differentiating EREMOTEIO errors in case an unsupported P2PDMA transfer is requested. When this happens, return BLK_STS_TARGET so the request isn't retried.
