4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nathan Fontenot <nf...@linux.vnet.ibm.com>
[ Upstream commit e722af6391949e8851310441bb0cec157d25611d ]
The failure path in ibmvnic_open() mistakenly makes a second call
to napi_enable instead of calling napi_disable. This can result
in a BUG_ON for any queues that were enabled in the previous call
to napi_enable.
