nfs-mount-monitor: strengthen fix_mount recovery sequence
Add lazy umount fallback, D-state process killer, stunnel restart, and
60-second hard deadline to prevent fix_mount from looping forever when
processes are stuck in D state on a stale NFSv4-over-stunnel mount.
Recovery sequence is now:
1. mount -o remount -f (cheap, no disruption)
2. kill_pinning_processes (SIGKILL D-state procs with nfs_ wchan)
3. umount -f (force unmount)
4. umount -l (lazy detach VFS node if -f failed)
5. systemctl restart stunnel + 2s sleep (refresh TLS transport)
6. mount (fresh mount)
The 60s deadline uses bash $SECONDS so fix_mount can never outlast its
own 10-second timer interval by an unbounded amount. Deployed to all
three r-nodes (r0/r1/r2) via rex nfs_mount_monitor.
