[PATCH 1/2] Don't traceback on read only (write protected) disks (#471883)

[Hans de Goede <hdegoede redhat com>]

This is a backport of a small part of commit:
http://git.fedorahosted.org/git/?p=anaconda.git;a=commitdiff;h=1380f13f0dad0108b8ed6ac02e249f53fb43156b

Which stops us from backtracing when we try to write a partitiontable to
a write protected disk (for example a writeprotected sdcard).
