[PATCH v2 2/3] PCI: endpoint: pci-epf-vntb: Align mw naming with config names

[Jerome Brunet]

The config file related to the memory windows start the numbering of
the MW from 1. The other NTB function does the same, yet the enumeration
defining the BARs of the vNTB function starts numbering the MW from 0.

Both numbering are fine I suppose but mixing the two is a bit confusing.
The configfs file being the interface with userspace, lets keep that stable
and consistently start the numbering of the MW from 1.
