Subject[PATCH 1/2] thunderbolt: Fix a leak in tb_retimer_add()
After the device_register() succeeds, then the correct way to clean up
is to call device_unregister(). The unregister calls both device_del()
and device_put(). Since this code was only device_del() it results in
a memory leak.

Fixes: dacb12877d92 ("thunderbolt: Add support for on-board retimers")

This is from a new static checker warning. Not tested. With new
warnings it's also possible that I have misunderstood something
fundamental so review carefully etc.
