Niklas Cassel a11497b3bb nvme-pci: don't simple map sgl when sgls are disabled ...

[ Upstream commit e51183be1f ]

According to the module parameter description for sgl_threshold,
a value of 0 means that SGLs are disabled.

If SGLs are disabled, we should respect that, even for the case
where the request is made up of a single physical segment.
