mchus 983f41a1f0 fix(nvidia): detect NVSwitch fabric via driver, not host-PCIe
On HGX B200 (Kaytus KR9288-X3) NVSwitch is managed via HMC/ERoT and never
appears on host lspci as 10de:0680, so the old check always returned
"not present" and silently skipped fabricmanager — leaving the fabric
untrained and CUDA/NCCL/dcgmi failing with "system not yet initialized"
on otherwise-healthy hardware. bee-check-nvswitch now checks, in order,
nvidia-smi's GPU Fabric GUID, /proc/driver/nvidia-nvswitch/devices, and
finally the legacy host-PCIe scan for older HGX generations.
