Btrfs: Fix async caching interaction with unmount
- don't stop the caching thread until btrfs_commit_super return. - if caching is interrupted by umount, set last to (u64)-1. otherwise the un-scanned range of block group will be considered as free extent. Signed-off-by: Chris Mason <chris.mason@oracle.com>
