Description

Since zram are not usable devices for Ceph, gather-facts should not return them.

e.g.

  "flash_count": 1,
  "flash_list": [
    {
      "description": "Unknown Unknown (66.6GB)",
      "dev_name": "zram0",
      "disk_size_bytes": 66597158912,
      "model": "Unknown",
      "rev": "Unknown",
      "vendor": "Unknown",
      "wwid": "Unknown" 
    }

The zram device is shown, but also it's capacity is reported incorrectly!

The gather-facts code should be excluding zram.
