[Piglit] [PATCH] util: Fix texture name returned by piglit_integer_texture()

[Chad Versace]

The function always returned texture name 0.  Fix to to return the
actual texture name.

Found by GCC warning:
    tests/util/piglit-util-gl.c:2623:1: warning: control reaches end of
         non-void function [-Wreturn-type]
