Ben Walker 8f7d9ec2f4 env/dpdk: Use the DPDK device count for IOMMU mapping
The VFIO container must have at least one device present to
be able to perform DMA mapping operations. Instead of using
the count of SPDK devices, use the count of DPDK devices. This
allows for the user of SPDK's memory management APIs even if
only a DPDK device is attached.
