When we recieved a command we incremented a stat counter depending on
the type of message. The problem is there were 8 types of commands but
there were only 4 counters allocated so it corrupted memory past the
end of the rxcmdpkt[] array.
The fix is just to remove the counters because they aren't used.

I don't think the layout of the stats struct matters, but I don't have
the hardware to test this.
