When running in fullscreen it is possible to end up in a situation
where we have more displays enabled than monitors. This can happen
if displays that were enabled in the previous connection to the guest
doesn't match displays requested when entering the fullscreen mode.
This commit solves the problem by disabling displays that should not
enabled in the fullscreen mode.
Resolves: rhbz#1212802

v1: https://www.redhat.com/archives/virt-tools-list/2015-April/msg00184.html
v2: - nth is not used to determine which display should be enabled,
but the list of fullscreen displays is used
- the extra display is disabled instead of being ignored
v3: - added missing check for self->priv->did_auto_conf to fix hidden display
when --reconnect
