btrfs: remove the extent item sanity checks in relocate_block_group
These checks are all taken care of for us by the tree checker code: - the flags don't change or are updated consistently - the v0 extent item format is invalid and caught in many other places too Reviewed-by: Qu Wenruo <wqu@suse.com> Signed-off-by: Josef Bacik <josef@toxicpanda.com> Reviewed-by: David Sterba <dsterba@suse.com> [ update changelog ] Signed-off-by: David Sterba <dsterba@suse.com>
