EAL -a and -b options are used to specify which PCI devices are
explicitly allowed or blocked during PCI bus scan.  This evaluation
is missing in the Windows implementation of rte_pci_scan.
This patch provides this missing functionality, so that apps can specify
which NetUIO devices to ignore during PCI bus scan.
