VPP-189 Addtional fixes for last coverity fix in linux_pci.c

Fix VPP startup problem where it cannot attach to a combination
of 3 Intel igb 1GE ports and 2 Intel ixgbe 10GE ports whose PCI
addresses are specified in the DPDK section of VPP startup
config file as follows:
dpdk { dev 0000:02:00.1 dev 0000:02:00.2 dev 0000:02:00.3
       dev 0000:05:00.0 dev 0000:05:00.1 }
