Subject: [PATCH 4.19 101/168] RDMA/core: Fix return error value in _ib_modify_qp() to negative

From: Li Heng <liheng40@...wei.com>

[ Upstream commit 47fda651d5af2506deac57d54887cf55ce26e244 ]

The error codes in _ib_modify_qp() are supposed to be negative errno.

Fixes: 7a5c938b9ed0 ("IB/core: Check for rdma_protocol_ib only after validating port_num")
