[cc1352,cc2652] add check before claiming transmit done (#5640)

Browse Source 
Check the global state in the radio when an ack frame is found before
reporting a transmit was completed. This change avoids the case where
an acknowledgment frame from another transmission is mistaken for our
acknowledgment frame.
