Subject: [PATCH 4.4 13/15] ntb_transport: Pick an unused queue

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

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

From: Thomas VanSelus <tvanselus@...-inc.com>

commit 8fcd0950c021d7be8493280541332b924b9de962 upstream.

Fix typo causing ntb_transport_create_queue to select the first
queue every time, instead of using the next free queue.
