[mcip-list] Patch fixing memory usage after device removal

[Michael K. <m-...@m-...>]

Hello list,

attached is a patch that fixes handling a device removal.

The for-loop with the state machine must not be continued in case a
device has been removed. Instead of introducing new flags to abort
the for-loop in such a case, I introduced a new state. A "bye" telegram
does not remove a device driver immediatelly but only marks it as a
zombie that can be removed at any time.
