Subject: [ 19/21] ntb_netdev: remove from list on exit

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

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

From: Jon Mason <jon.mason@...el.com>

commit 904435cf76a9bdd5eb41b1c4e049d5a64f3a8400 upstream.

The ntb_netdev device is not removed from the global list of devices
upon device removal.  If the device is re-added, the removal code would
find the first instance and try to remove an already removed device.
