[S390] dasd: Use default recovery for SNSS requests
For extended error reporting we sometimes have to start an Sense Subsystem Status request (SNSS). When this request needs to be recovered for some reason, the recovery request will fail with 'command reject'. Our usual recovery procedure will retry the failed request by creating a new request and chaining the failed request from that one. SNSS requests, though, must not be chained from anything, so the recovery request will fail permanently. Use the default recovery for SNSS request, which will just restart the original request without further ado.
