[PATCH v3] net: usb: pegasus: fixes of set_register(s) return value evaluation;

  - restore the behavior in enable_net_traffic() to avoid regressions - Jakub
    Kicinski;
  - hurried up and removed redundant assignment in pegasus_open() before yet
    another checker complains;

  v3:
     Added CC: stable@vger.kernel.org in a vague hope this time it'll go in;
