env_dpdk: add dpdk_pci_device_get_name

Browse Source 
This touches the rte_pci_device structure, so let's
make a separate accessor function just for that.

We will start putting the definitions for these
new dpdk_pci_device_xxx functions at the end of
pci.c.  At the end of this series, we will then
just lop off the end of pci.c containing all of
the dpdk_pci_device functions and move them to
a DPDK-dependent pci_22_07.c file.
