Properly delete csum item in btrfs_truncate_in_trans.
When 'item_end' is equal to 'inode->i_size', 'found_type' is updated and current item is skipped. This behavior is correct for extent item, but incorrect for csum item. For example, there is a csum item with 'offset == 0'. When deleting the inode, 'inode->i_size' is set to 0, so the csum item isn't deleted. Signed-off-by: Chris Mason <chris.mason@oracle.com>
