net: thunderbolt: Fix the parameter passing of tb_xdomain_enable_paths()/tb_xdomain_d...

[ Upstream commit 8ec31cb17cd355cea25cdb8496d9b3fbf1321647 ]

According to the description of tb_xdomain_enable_paths(), the third
parameter represents the transmit ring and the fifth parameter represents
the receive ring. tb_xdomain_disable_paths() is the same case.

[Jakub] Mika says: it works now because both rings ->hop is the same
