thunderbolt: dma_test: Use correct value for absent rings when creating paths

Browse source

commit 70c2e03e9a upstream.

Both tb_xdomain_enable_paths() and tb_xdomain_disable_paths() expect -1,
not 0, if the corresponding ring is not needed. For this reason change
the driver to use correct value for the rings that are not needed.
