This commit fixes key_id_mode handling and added exception handling
when key_id_mode is 0.
According to IEEE Std 802.15.4-2015, when Key Id Mode is 0x00:
Key is determined implicitly from the originator and recipient(s)
of the frame, as indicated in the frame header.
Our test scripts cannot handle such packets. If we leave key_id_mode =
0 case unhandled, we would get some exceptions that may cause
developers to think that something is wrong. However dropping packets
in this case is a normal behavior.
