mkiss: fix scribble on freed memory

commit c53d2122e3b634fb49ca1ff4bb53c6d8d5966da3 fixed a user triggerable
scribble on free memory but added a new one which allows the user to
scribble even more and user controlled data into freed space.

As with 6pack we need to halt the queue before we free the buffers, because
the transmit logic is not protected by the semaphore.
