fix: workaround problems with udevd races

When `udevd` rescans block device partitions while Talos is doing
partitions, it might be that Talos can hit the following error
while trying to open/mount a partition:

```
no such device or address
```

Previous attempts to fix that were using `ENODEV`, while the proper code
is `ENXIO`.

Also take exclusive lock while working with user disks to prevent
concurrent udevd rescan.
