For P2P requests, we must use the pci_p2pmem_map_sg() function
instead of the dma_map_sg functions.
With that, we can then indicate PCI_P2P support in the request queue.
For this, we create an NVME_F_PCI_P2P flag which tells the core to

The DMA address used when mapping PCI P2P memory must be the PCI bus

Memory mapped in this way does not need to be unmapped and thus if we
