 Description   

After landing LU-5073 request can get stuck in following state
crash> ptlrpc_request.rq_receiving_reply,rq_req_unlink,rq_reply_unlink,rq_net_err,rq_timedout,rq_status,rq_bulk,rq_waiting,rq_resend,rq_xid,rq_phase 0xffff8807d68e7c00
rq_receiving_reply = 0
rq_req_unlink = 0
rq_reply_unlink = 0
rq_net_err = 0
rq_timedout = 0
rq_status = -11
rq_bulk = 0xffff881035e32000
rq_waiting = 0
rq_resend = 1
rq_xid = 1471081167901408
rq_phase = RQ_PHASE_UNREGISTERING

It is needed to call ptlrpc_unregister_bulk() to become ptlrpc_client_bulk_active() equal to 0
