[PATCH v3 5/7] thunderbolt: Mark discovered tunnels as active

[Sven Peter <sven@kernel.org>]

Discovered tunnels that have been activated by whatever was running
before us stay in TB_TUNNEL_INACTIVE until hibernation restore such that
anything depending on tb_tunnel_is_active() skips them. Mark them active
during discovery instead. These now also emit TUNNEL_EVENT=activated
uevents during discovery.

Fixes: d6d458d42e1e ("thunderbolt: Handle DisplayPort tunnel activation asynchronously")
