Subject: net: thunderbolt: Tear down connection properly on suspend

From: Mika Westerberg <[email protected]>

commit 8e021a14d908475fea89ef85b5421865f7ad650d upstream.

When suspending to mem or disk the Thunderbolt controller typically goes down as well tearing down the connection automatically. However, when suspend to idle is used this does not happen so we need to make sure the connection is properly disconnected before it can be re-established during resume.
