Subject: [PATCH 4.8 50/67] IB/rxe: Update qp state for user query

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

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

From: Yonatan Cohen <yonatanc@...lanox.com>

commit 6d931308f55faaef3f30bd0346c47f99528b229d upstream.

The method rxe_qp_error() transitions QP to error state
and make sure the QP is drained. It did not though update
the QP state for user's query.

This patch fixes this.
