Bluetooth: Don't check encryption for L2CAP raw sockets
For L2CAP sockets with medium and high security requirement a missing encryption will enforce the closing of the link. For the L2CAP raw sockets this is not needed, so skip that check. This fixes a crash when pairing Bluetooth 2.0 (and earlier) devices since the L2CAP state machine got confused and then locked up the whole system.
