File libparted-dasd-update-and-improve-fdasd-functions.patch of Package parted

From: Wang Dong <dongdwdw@linux.vnet.ibm.com>
Date: Wed, 26 Oct 2016 04:22:47 +0200
Subject: libparted/dasd: update and improve fdasd functions
References: fate#321531
Patch-mainline: v3.3
Git-commit: db37c8c017ebef8f241420dda071940957d4bbe5

Update the fdasd_anchor_t data structure and the fdasd_cleanup()
function. Also correct vtoc_changed and vlabel_changed accounting
because they are important to rewrite vtoc to save the changes.
