dpdk: only look at PCI information on PCI devices
The rte_device is use as a base type of all DPDK devices. It is not valid to use container_of to find PCI information unless the bus of the rte_device is pci. Otherwise, the pointer is looking at some other data, which may or may not be zero. This change introduces a helper function to get rte_pci_device pointer. If device is on PCI bus it returns pointer to rte_pci_device info, otherwise it returns NULL.
