[PATCH 1/2] Btrfs: fix wrong missing device counter decrease
The missing devices are accounted by its own fs device, for example the missing devices in seed filesystem will be accounted by the fs device of the seed filesystem, not by the new filesystem which is based on the seed filesystem, so when we remove the missing device in the seed filesystem, we should decrease the counter of its own fs device. Fix it.
