mkiss: fix scribble on freed memory

commit c8e29f9fc28f6886a0535f5894e7f608b68efdc8 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.
