dm: vdisplay: Add physical monitor id check. 

vdisplay use physical monitor id(pscreen index) to locate the monitor.
The max index value always is the physical monitor number - 1. For
example, there are 4 physical monitors connected. The monitor id should
be 0, 1, 2 and 3. We need check monitor id that user inputs and make
sure it is in a correct range.
