Johan Hovold 10b7b676b7 can: ucan: fix devres lifetime ...

commit fed4626501 upstream.

USB drivers bind to USB interfaces and any device managed resources
should have their lifetime tied to the interface rather than parent USB
device. This avoids issues like memory leaks when drivers are unbound
without their devices being physically disconnected (e.g. on probe
deferral or configuration changes).

Fix the control message buffer lifetime so that it is released on driver
unbind.
