Btrfs: fix OOPS of empty filesystem after balance
btrfs will remove unused block groups after balance. When a empty filesystem is balanced, the block group with tag "DATA" may be dropped, and after umount and mount again, it will not find "DATA" space_info and lead to OOPS. So we initial the necessary space_infos(DATA, SYSTEM, METADATA) to avoid OOPS. Reported-by:Daniel J Blueman <daniel.blueman@gmail.com> Signed-off-by:
