s_blockfile_groups is used to limit allocations for non-extent files to block groups with block numbers less than 2^32. However, it's not updated when the filesystem is resized online, so the new groups are unavailable to non-extent files until a remount. Fix this by updating the value in ext4_update_super() at resize time.
