btrfs: clear defrag status of a root if starting transaction fails
commit 6819703f5a365c95488b07066a8744841bf14231 upstream.
The defrag loop processes leaves in batches and starting transaction for
each. The whole defragmentation on a given root is protected by a bit
but in case the transaction fails, the bit is not cleared
In case the transaction fails the bit would prevent starting
defragmentation again, so make sure it's cleared.
