[Intel-gfx] [PATCH igt 5/6] lib/igt_fb: fix igt_get_all_formats documentation

[Paulo Zanoni]

We give the callers a const pointer to a static variable that we reuse
between multiple calls: they're not supposed to free it, and they
don't free it today.

Fix the documentation and leave the still reachable pointer instead of
reworking the function and its callers.
