Function pci_num_vf() is introduced from upstream linux-2.6.34. So this patch make compatible with longterm kernel linux-2.6.32.63.
For RHEL6's kernel, although it is based on linux-2.6.32, it has pci_num_vf() implementation. As the same with commit 11ba0426, pci_num_vf() is defined from RHEL6. So we should check the macro RHEL_RELEASE_CODE to consider this situation.
