Mixing GPUs that support rebar and ones that do not does not work with this driver

[vektorprime]

I have 2x RTX 3090 with rebar and 2x RTX 3080 (20GB) modded that do not support rebar. The P2P driver says thatt even the 3080 support P2P so it causes crashes in llama cpp when I enable P2P. The firmware on the 3080 is locked so I can never update it to use get rebar. Could we only enable this for GPUs that actually support it?

I ended up just having an LLM write a small patch for this and it worked:
