[dx99] Mafia Demo patch for bug #1670

[Jason Edmeades]

Sorry - been too busy for wine recently, but have just started to get 
those urges again... Started with a reported d3d8 bug, #1670 which 
occurs when you crash into a lamp post. The application did a draw with 
a vertex shader followed by a call to the odd drawprimitiveUP, and I 
forgot to check a flag which meant we tried to use multiple streams 
which were not set up and hence trapped.

Changelog

Fix the draw*primitiveUP calls so they work directly after a draw which 
uses vertex shaders.
