[WINED3D 6] Improve GetAdapterMonitor stub

[Ivan Gyurdiev]

Don't return WINED3D_OK, that's completely invalid.
Returning something like...the primary monitor [ lacking multi-monitor 
support, or multi-device support at the moment ].

This fixes 2 demos for the most part (from humus.ca):
SelectiveSuperSampling
Hair

..because they were computing window dimensions based on monitor 
properties obtained from our invalid handle.
