[PATCH 6.6 02/14] thunderbolt: Use tb_tunnel_dbg() where possible to make logging more consistent

[Alexandru Gagniuc]

From: Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx>

[ Upstream commit fe8a0293c922ee8bc1ff0cf9048075afb264004a ]

This makes it easier to find out the tunnel in question. Also drop a
couple of lines that generate duplicate information.
