Resolves:https://bugzilla.redhat.com/show_bug.cgi?id=923053
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".

Correct XML:
    <disk type='block' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <source dev='/dev/sdb'/>
      <target dev='vdb' bus='virtio'/>
      <readonly/>
    </disk>

And, this patch supports cdrom with volume type for change-media command
For example:

'/var/lib/libvirt/images/boot.iso' is a volume path of 'boot.iso' volume
on 'default' pool and the cdrom device has no source.

Virsh command:
 virsh change-media rhel6qcow2 vdb /var/lib/libvirt/images/boot.iso --insert

The updated disk XML:
    <disk type='volume' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <source pool='default' volume='boot.iso'/>
      <target dev='vdb' bus='virtio'/>
      <readonly/>
    </disk>
