[PATCH 2/3] wined3d: Clear the graphics pipeline key stencil test state when the stencil test is disabled.

[Henri Verbeet]

The state itself is ignored in this case, but could still cause additional
pipeline variants to be created. That's mostly a consideration for Direct3D 9
and before, since Direct3D 10 and 11 already normalise disabled stencil test
state themselves.
