nvme-pci: don't limit DMA segement size
NVMe uses PRPs (or optionally unlimited SGLs) for data transfers and
has no specific limit for a single DMA segement. Limiting the size
will cause problems because the block layer assumes PRP-ish devices
using a virt boundary mask don't have a segment limit. And while this
is true, we also really need to tell the DMA mapping layer about it,
otherwise dma-debug will trip over it.
