thunderbolt: Serialize PCIe tunnel creation with PCI rescan
commit a03e828915c00ed0ea5aa40647c81472cfa7a984 upstream.
We need to make sure a new PCIe tunnel is not created in a middle of
previous PCI rescan because otherwise the rescan code might find too
much and fail to reconfigure devices properly. This is important when
native PCIe hotplug is used. In BIOS assisted hotplug there should be no
such issue.
