scene: mark the EGL context as failed when the VBO map fails

When mapping the streaming vertex buffer failed, the code called
EglContext::isFailed(), which is a read-only getter and does nothing,
defeating the intended recovery path. Call setFailed() instead so the
context is marked as broken and gets recreated by the compositor.
