[PATCH 4.18 043/145] IB/srpt: Fix srpt_cm_req_recv() error path (2/2)

[Greg Kroah-Hartman]

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

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

From: Bart Van Assche <bart.vanassche@xxxxxxx>

commit 6869e0004fe16184acd6488f0c637e0081a84a8a upstream.

If a login request was received through the RDMA/CM and if an error occurs
during login, clear rdma_cm_id->context instead of ib_cm_id->context.

Fixes: 63cf1a902c9d ("IB/srpt: Add RDMA/CM support")
