Subject: [PATCH 3.4 70/88] target: use correct sense code for LUN communication failure

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hannes Reinecke <hare@...e.de>

commit 18a9df42d53fabfa43b78be1104838cc8b9762e1 upstream.

The ASC/ASCQ code for 'Logical Unit Communication failure' is
0x08/0x00; 0x80/0x00 is vendor specific.
