AX.25 cb lookup patch

[Ralf Baechle <ralf@xxxxxxxxxxxxxx>]

Ax AX.25 connection is identified only by it's source and destination,
not by the device it's routed through, so fix the connection block
lookup to ignore the device of a connection.  This fixes dying connections
in case of an AX.25 routing flap.
