[ Upstream commit 7482d9cb5b974b7ad1a58fa8714f7a8c05b5d278 ]
Cited patch missed to extract PCI pf number accurately for PF and VF port flavour. It considered PCI device + function number. Due to this, device having non zero device number shown large pfnum.
Hence, use only PCI function number; to avoid similar errors, derive pfnum one time for all port flavours.
