Bluetooth: Mesh: Fixes Friend Queue store message

Browse source 
If the SRC field of the received message is a unicast
address of an element of the Low Power node, then the
message shall not be stored in the Friend Queue.

Otherwise, lpn will discard this message, eventually
it breaks friendship.

Fixes: #30657
