rdma/cxgb4: Fixes cxgb4 probe failure in VM when PF is exposed through PCI Passthrough
Change logic which determines our Physical Function at PCI Probe time.
Now we read the PL_WHOAMI register and get the Physical Function.
Pass Physical Function to Upper Layer Drivers in lld_info structure in the
new field "pf" added to lld_info. This is useful for the cases where the
PF, say PF4, is attached to a Virtual Machine via some form of "PCI
Pass Through" technology and the PCI Function shows up as PF0 in the VM.
