[PATCH 1/2] thunderbolt: Fix a leak in tb_retimer_add()

[Dan Carpenter <dan.carpenter@oracle.com>]

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.

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.
