slabtop: let's stop always ignoring the last slab node

Browse Source 
This patch will fix a fencepost error that has existed
since at least 2004, the result of which was to always
completely ignore that last merged / sorted slab node.

[ Of course, little harm was done since output would ]
[ have been limited to a terminal's height. Thus, it ]
[ would have required a huge display before noticed. ]

[ But, now that the run once switch shows everything ]
[ such an omission would become really unforgivable. ]
