thunderbolt: Correct path indices for PCIe tunnel

[ 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.
