[ Upstream commit ce19f91eae43e39d5a1da55344756ab5a3c7e8d1 ]
PCIe tunnel path indices got mixed up when we added support for tunnels between switches that are not adjacent. This did not affect the functionality as it is just an index but fix it now nevertheless to make the code easier to understand.
