[Vinson Lee]

This patch fixes these GCC maybe-uninitialized warnings.

tex3d-maxsize.c: In function 'piglit_display':
tex3d-maxsize.c:123:15: warning: 'depth' may be used uninitialized in this function [-Wmaybe-uninitialized]
   glTexImage3D(GL_TEXTURE_3D, 0, GL_RGBA8, width, height, depth, 0,
               ^
tex3d-maxsize.c:123:15: warning: 'height' may be used uninitialized in this function [-Wmaybe-uninitialized]
