Mika Westerberg acb40d8412 thunderbolt: Initialize Thunderbolt bus earlier
The 0day kbuild robot reports following crash:

  BUG: unable to handle kernel NULL pointer dereference at 00000004

The reason is that both Thunderbolt bus and thunderbolt-net are build
into the kernel image, and the latter is linked first because
drivers/net comes before drivers/thunderbolt. Since both use
module_init() thunderbolt-net ends up calling Thunderbolt bus functions
too early triggering the above crash.

Fix this by moving Thunderbolt bus initialization to happen earlier to
make sure all the data structures are ready when Thunderbolt service
drivers are initialized. To be on the safe side also add a check for
properly initialized xdomain_property_dir to tb_register_property_dir().
