Add NVMeSubsystemClass() method to sysfs.FS that reads /sys/class/nvme-subsystem/ to discover NVMe over Fabrics subsystems and their controller paths. For each subsystem it reads the NQN, model, serial, I/O policy, and enumerates controllers with their state, transport, and address. This complements the existing NVMeClass() (which reads per-controller hardware info from /sys/class/nvme/) by providing subsystem-level path redundancy data. All read errors are propagated to the caller. Signed-off-by: Shirly Radco <sradco@redhat.com> Co-authored-by: AI Assistant <noreply@cursor.com>

This is the parsing layer for prometheus/node_exporter#3579
