[2/2] wined3d: Fix the stretch_rect_fbo() declaration to match the implementation

[H. Verbeet]

This is extracted from Parallels' modified wined3d source, so credit
should go to SWsoft.
Looks pretty harmless to me, but MSVC will probably complain.

Changelog:
  - Fix the stretch_rect_fbo() declaration to match the implementation
