4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mustafa Ismail <mustafa.ismail@xxxxxxxxx>
[ Upstream commit f20d429511affab6a2a9129f46042f43e6ffe396 ]
The iWARP Exception Queue (IEQ) resources are not freed when a QP is
destroyed. Fix this by freeing IEQ resources when freeing QP resources.
Fixes: d37498417947 ("i40iw: add files for iwarp interface")
