Clear the high order bit from the destination call number before sending.

send_apathetic_reply takes the incoming frame's source call number as the
destination call number for the outgoing frame.  If the incoming frame was a
full frame, then the high order bit of the source call number is set and will be
interpreted as a retransmit when sent back out as the destination call number.
