Btrfs: fix memory leak of empty filesystem after balance
After Josef's patch(commit 3c14874acc71180553fb5aba528e3cf57c5b958b),
btrfs will exclude super bytes when reading block groups(by marking a extent
state UPTODATE). However, these bytes do not get freed while balance remove
unused block groups, and we won't process those removed ones any more, when
we do umount and unload the btrfs module, btrfs hits a memory leak.
This patch add the missing free operation.
Reproduce steps:
$ mkfs.btrfs disk
$ mount disk /mnt/btrfs -o loop
$ btrfs filesystem balance /mnt/btrfs
$ umount /mnt/btrfs
$ rmmod btrfs
