Logan Gunthorpe b54369a248 NTB: perf: Fix support for hardware that doesn't have port numbers ... Legacy drivers do not have port numbers (but is reliably only two ports) and was broken by the recent commit that added mult-port support to ntb_perf. This is especially important to support the cross link topology which is perfectly symmetric and cannot assign unique port numbers easily. Hardware that returns zero for both the local port and the peer should just always use gidx=0 for the only peer.
