d59659340c i40iw: Add missing cleanup on device close
On i40iw device close, disconnect all connected QPs by moving
them to error state; and block further QPs, PDs and CQs from
being created. Additionally, make sure all resources have been
freed before deallocating the ibdev as part of the device close.

0fc2dc5889 i40iw: Add Quality of Service support
Add support for QoS on QPs. Upon device initialization,
a map is created from user priority to queue set

set handle for use with the QP.
