check_pcie_links() warns when an NVMe drive negotiates fewer lanes than it
supports — almost always motherboard lane-sharing (a GPU/second card or another
M.2 stealing lanes), the case the user asked about — and reports speed-only
reductions as info (slower slot / idle ASPM). GPU is excluded: NVIDIA drops its
PCIe gen+width at idle, so a snapshot would false-alarm. Reuses inventory
read_link/nvme_controllers (refactored to public). Wired into run_health_checks;
+tests. Folded into the 0.38.0 PCIe work.
