thunderbolt: Do not tear down tunnels when driver is unloaded
Now that we have capability to discover existing tunnels during driver load there is no point tearing down tunnels when the driver gets unloaded. Instead we can just leave them running. If user disconnects devices while there is no Thunderbolt driver loaded, tunneled protocol hotplug happens and is handled by the corresponding driver (pciehp in case of PCIe tunnel, GFX driver in case of DP tunnel).
