[Bug 1916968] [NEW] fwupd suggests wrong firmware updates on LG gram laptop

[Jeongbin Park]

Public bug reported:

Ubuntu release:
Ubuntu 18.04.5 LTS

The version of the package:
```
$ apt-cache policy fwupd
fwupd:
  Installed: 1.2.10-1ubuntu2~ubuntu18.04.5
  Candidate: 1.2.10-1ubuntu2~ubuntu18.04.5
  Version table:
 *** 1.2.10-1ubuntu2~ubuntu18.04.5 500
        500 http://de.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages
        100 /var/lib/dpkg/status
     1.0.6-2 500
        500 http://de.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
```

What expected to happen:
No firmware updates suggested.

What happened instead:
On an LG laptop (which is not mine, model name 14ZD970-GX70K), the software update suggests updating the system firmware to the wrong one, "ThinkPad X1 Yoga 3rd Corporate ME Update" (version 184.80.3746). This would be a bug of 'fwupd', since the snap 'gnome-firmware' also suggests the wrong firmware is one of the releases of the current system firmware "14ZD970-GX70K System Firmware" (version 1.21.37898). After confirming the update, the laptop restarted, went into the firmware update mode, and then stuck on it forever. After force rebooting the machine, (thankfully) it was returned back to the normal Ubuntu session.
