egl: make eglSwapInterval a no-op for !window surfaces
As the spec says, the function is a no-op when the surface is not a
window one.
That spec implies that EGL_TRUE should be returned in that case, yet
the ARM driver seems to return EGL_FALSE + EGL_BAD_SURFACE.
The Nvidia driver returns EGL_TRUE. We follow that behaviour until a
decision is made.
