nvapi-gpu: Simplify work around

[jp7677]

No need to initialize everything for the-last-of-us.

Much less code and also addresses a justified review comment from the initial work around. Waiting for confirmation ...

(Follow up from #117)

Confirmed on LDG that this variation is also fine for The Last of Us.
