wined3d: Report the correct number of available 4-component float vectors for GLSL

[Mirek]

This patch caused regresion in Half-Life 2 Episode One, if i have 
"UseGLSL"="enabled" HalfLife 2 Episode One crash about 20 seconds after 
start and menu page is completly white! Only the second part (second 
gl_max /= 4;) is the bad one, with first part evrything works well.

> GL_MAX_VERTEX_UNIFORM_COMPONENTS_ARB and
> GL_MAX_FRAGMENT_UNIFORM_COMPONENTS_ARB return the number of available
> uniform components. A 4-component float vector need 4 uniform
