[PATCH 5.10 287/663] RDMA/rtrs-srv: Release lock before call into close_sess

[Greg Kroah-Hartman]

From: Jack Wang <jinpu.wang@xxxxxxxxxxxxxxx>

[ Upstream commit 99f0c3807973359bba8f37d9198eea59fe38c32a ]

In this error case, we don't need hold mutex to call close_sess.

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