greybus: audio: Cleanup GB protocol connections in case of abrupt codec removal
We need to clean up GB protocl connections, otherwise successive
codec insertions fails repeatedly.
NOTE: As per suggestion, since codec is already removed, one should
not trigger any GB command. It'll cause a delay of atleast TIMEOUT
value.
HOwever, failing to cleanup GB protocol, causes successive module
insertion to fail
