Bug#963475: Could not parse device path: Invalid argument

[Michel Le Bihan]

Hello,

I tested `efibootmgr -v` from Debian testing in QEMU and had the `Could
not parse device path: Invalid argument` error. Then I downloaded
Fedora 32 live, run `efibootmgr -v` and got a nice output:
```
[liveuser@localhost-live ~]$ sudo efibootmgr -v
BootCurrent: 0001
Timeout: 0 seconds
BootOrder: 0001,0000,0005

```

I think that the Debian package should have this patch applied.
