be2net: remove usage of be_pci_func

When PCI functions are virtuialized in applications by assigning PCI
functions to VM (PCI passthrough), the be2net driver in the VM sees a

different function number. So, use of PCI function number in any
calculation will break existing code. This patch takes care of it.
