ext4: Convert bg_inode_bitmap and bg_inode_table
Convert bg_inode_bitmap and bg_inode_table to bg_inode_bitmap_lo and bg_inode_table_lo. This helps in finding BUGs due to direct partial access of these split 64 bit values Also fix one direct partial access Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
