Subject: [PATCH] virsh: fix change-media bug on disk block type

Resolves:https://bugzilla.redhat.com/show_bug.cgi?id=923053
(cherry picked from commit 7729a16814d5bf3aebd248c9af00296ae2773818)

When cdrom is block type, the virsh change-media failed to insert
source info because virsh uses "<source block='/dev/sdb'/>" while
the correct name of the attribute for block disks is "dev".
