direct3d: Remove unnecessary render target support check.

Direct3D 9 dictates that caps.NumSimultaneousRTs must always be at least 1,
which is to say that Direct3D 9 level hardware must always support render
targets.

(caps.NumSimultaneousRTs is meant to show if you can draw to multiple render
targets in a single draw call.)

We had already hardcoded SDL_RENDERER_TARGETTEXTURE as available earlier in
the function anyhow.

Fixes #4781.
