thunderbolt: Handle ERR_LOCK notification
If the USB4 router downstream port is locked, sending configuration
packet to a router below it causes ERR_LOCK to be sent. Instead of warn
splat about unknown error we log the error (just warning level) and
return -EACCESS instead. The idea is that we may want to do something
when such error code is received, like perform unlock.
