There is a logical error in igb_uio/compat.h when define pci_num_vf().
Only CONFIG_PCI_IOV enabled, this function could be defined.

This patch fix the following error for linux-2.6.32.63:
CC [M]  /root/dpdk-source/build/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.o
/root/dpdk-source/build/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.c: In function ‘show_max_vfs’:
/root/dpdk-source/build/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.c:75: error: implicit declaration of function ‘pci_num_vf’
