ext4: sync up block group descriptor with e2fsprogs. From: Coly Li This patch extends bg_itable_unused of ext4 group descriptor from 16bit into 32bit. In order to add bg_itable_unused_hi into struct ext4_group_desc, some extra fields which are already introduced into e2fsprogs are also added in for consistency.
