Message:

Additions: X11: fix guest screen handling in multi-monitor setup, bugref:9637, bugref:10222.

This commit restores guest screen count calculation in VBoxVGA and VBoxSVGA graphics configuration.
This in turn resolves the issue with improper mouse pointer positioning on screen 0 under certain
circumstances when guest is running multi-monitor setup.
