gdk/win32: fix `hr` set but not used

A number of warnings are produced:

[23/1038] Compiling C object gdk/win32/libgdk-win32.a.p/gdkinput-dmanipulation.c.obj
../gdk/win32/gdkinput-dmanipulation.c: In function 'reset_viewport':
../gdk/win32/gdkinput-dmanipulation.c:354:11: warning: variable 'hr' set but not used [-Wunused-but-set-variable]
  354 |   HRESULT hr;
      |           ^~

Try to do something sensible instead.
