Oleksij Rempel b43e3a82bc can: j1939: transport: j1939_simple_recv(): ignore local J1939 messages send not by J1939 stack 
In current J1939 stack implementation, we process all locally send
messages as own messages. Even if it was send by CAN_RAW socket.

To reproduce it use following commands:
testj1939 -P -r can0:0x80 &
cansend can0 18238040#0123

This step will trigger false positive not critical warning:
j1939_simple_recv: Received already invalidated message

With this patch we add additional check to make sure, related skb is own
echo message.

Fixes: 9d71dd0c70 ("can: add support of SAE J1939 protocol")
