[PATCH 1/3] PCI: endpoint: pci-epf-vntb: Pass PF/VF number when BAR programming

[Koichiro Den]

vntb_epf_mw_set_trans() programs the memory-window BAR through
pci_epc_set_bar() with hardcoded function numbers (0, 0), so the BAR
lands on the wrong function whenever the vNTB EPF is bound to anything
but PF0. The other BAR programming sites in the vNTB driver already pass
the EPF's own numbers.

Pass the EPF's own func_no/vfunc_no here as well.

Fixes: e35f56bb0330 ("PCI: endpoint: Support NTB transfer between RC and EP")
