thunderbolt: Wait for tb_domain_release() to complete when driver is removed
We should not call nhi_shutdown() before the domain structure and the
control channel rings are completely released. Otherwise we might
release resources like the nhi->msix_ida that are still referenced in
tb_domain_release(). For this reason wait for the tb_domain_release() to
be completed before continuing to nhi_shutdown() and eventually
releasing of the rest of the data structures.
