[PATCH v2] scsi: iscsi: Fix redundant response for ISCSI_UEVENT_GET_HOST_STATS request

[Xiang Zhang]

The ISCSI_UEVENT_GET_HOST_STATS request is already replied to iscsid in iscsi_get_host_stats,
This fix ensures that redundant responses are skipped in iscsi_if_rx.
- On success: send reply and stats from iscsi_get_host_stats()
  within if_recv_msg().
- On error: fall through.
