OBSERVED RESULT when bug occurs
SUMMARY
When using `btrfs device add` to add a new partition (I do not try for adding a
new device), `partitionmanager` will probably not show condition of added
partition correctly, like it cannot show the usage rate of device.
This problem does not always happen. Just keep rebooting and opening
`partitionmanager` and sometimes (but rarely) this problem will disappear, but
it will still exist after reboot.
STEPS TO REPRODUCE
1. make two BTRFS partitions nad mount one of them in `fstab`
2. `sudo btrfs device add -f /dev/$A $B`, whre `$A` is the path name of the
second partition and `$B` is the mounted path of the first partition
3. Open `partitionmanager`, This problem will probably exist. If no, reboot and
probably exist. (Like 8 in 10 chance)
