[PATCH 05/11] wined3d: Fix shader_resource_view_generate_mipmaps() with texture views.

Józef noticed that GL_TEXTURE_BASE_LEVEL and GL_TEXTURE_MAX_LEVEL are
specified to be relative to the view, not to the original
texture. That mostly means that we don't want to set them here if we
have a texture view.
