gapir/windows/gles_renderer: Don't rage-quit if tear-down errors.

There's not much to gain by quitting GAPIR at this point. In my experience tear-down functions tend to be more buggy than setup & core functions.

Assuming there's a real error being raised, these still get logged. Setup errors are still fatal, so assuming context creation succeeded, there's now at least the possibility that something renders.
