[ Impact ]

A use-after-free is possible if two functions in `i3c/master`
enter a race condition. In order to ensure that this can no longer
occur, we invalidate any related work when unregistering a `i3c`
device so that it cannot then be used to access the underlying
freed value.

[ Fix ]

jammy: backported from upstream, simply applying the change despite
       a missing commit which caused contextual differences.

[ Tests ]

Compile and boot tested.

[ Where problems could occur ]

One-line change with limited backport-related regression potential.
Since the scope is limited to i3c, the most that could happen is a
denial of that specific service. (although this is quite unlikely)
