Subject: [PATCH 5.11 023/104] RDMA/rtrs-srv: Do not signal REG_MR

From: Jack Wang <jinpu.wang@...ud.ionos.com>

commit e8ae7ddb48a1b81fd1e67da34a0cb59daf0445d6 upstream.

We do not need to wait for REG_MR completion, so remove the
SIGNAL flag.

Fixes: 9cb837480424 ("RDMA/rtrs: server: main functionality")
