thunderbolt: Don't disable lane adapter if XDomain lane bonding isn't possible
This happens when firmware connection manager is being used. It will
deal with disabling the lane 1 adapter after the tunnel has been
established and re-enabling it afterwards. For this reason only do this
when we know that lane bonding is possible (e.g running software
connection manager).
