utils/hwloc-calc: cleanup topology options management
Enforce those options (--restrict/-i/--disallowed) at the beginning of
the command-line instead of reupdating the topology later if options
and locations are mixed.
Try to document this but we don't show a precise error message if
--restrict/-i/... is given too late.
