The vivid driver supports the <Vendor Command With ID> message,
but if the Vendor ID of the received message didn't match the Vendor ID
of the CEC Adapter, then it ignores it (good) and returns 0 (bad).
It should return -ENOMSG to indicate that other followers should be
asked to handle it. Return code 0 means that the driver handled it,
which is wrong in this case.
As a result, userspace followers never get the chance to process such a
message.
Refactor the code a bit to have the function return -ENOMSG at the end,
drop the default case, and ensure that the message handlers return 0.
That way 0 is only returned if the message is actually handled in the
vivid_received() function.
