[31/49] wined3d: Pass the correct mask to shader_glsl_add_src_param() in pshader_glsl_texm3x2depth()

[H. Verbeet]

The call to shader_glsl_add_dst_param() is redundant. The destination
is always gl_FragDepth, which is a float and can't have a write mask.

Changelog:
  - Pass the correct mask to shader_glsl_add_src_param() in
pshader_glsl_texm3x2depth()
