[Intel-gfx] [PATCH gpu-tools] gem_vmap_blits: fix compilation if I915_PARAM_HAS_VMAP is not defined

[Paulo Zanoni]

Previously, "make check" failed because the main() function was not
defined.

We could also try to move the logic outside the file and let autoconf test for
vmap, so we wouldn't even try to compile the file. If you prefer, I can
implement this too.
