Subject: [PATCH 5.4 232/408] RDMA/hns: Set the unsupported wr opcode

From: Lijun Ou <oulijun@...wei.com>

[ Upstream commit 22d3e1ed2cc837af87f76c3c8a4ccf4455e225c5 ]

hip06 does not support IB_WR_LOCAL_INV, so the ps_opcode should be set to
an invalid value instead of being left uninitialized.

Fixes: 9a4435375cd1 ("IB/hns: Add driver files for hns RoCE driver")
Fixes: a2f3d4479fe9 ("RDMA/hns: Avoid unncessary initialization")
