Revert "egl: Don't add hardware device if there is no render node v2."

This reverts commit 5743a36b2b32a91eaf82c8d109932fe4fea01233.

Now that _eglAddDevice is always called with the correct software
hint, no need to bail out if the device doesn't have a render node.
On split render/display SoCs, the DRM device won't have a render
node, yet rendering is hardware-accelerated (via kmsro).
