mm: show free swap as signed
Adjust <Alt><SysRq>m show_swap_cache_info() to show "Free swap" as a signed long: the signed format is preferable, because during swapoff nr_swap_pages can legitimately go negative, so makes more sense thus (it used to be shown redundantly, once as signed and once as unsigned).
