guest-diag: scanner EOF guard + exclude non-client nvidia fd holders
Two failure modes found when the scanner detects clients by device fd:
a transient boot nvidia-smi was picked and its exited pagemap read back
EOF, and scan_window advanced by got=0 forever (busy spin, no stream);
and non-client nvidia fd holders must never be committed to. Break on
got<=0 in scan_window (scan_range already did), skip nvidia-smi/
persistenced/Xorg, and prefer /dev/nvidia-uvm holders.
