lguest: clear cached last cpu when guest_set_pgd() called. commit v3.9-rc1-53-g6d0cda9 "lguest: cache last cpu we ran on." missed one case, which causes a triple fault. The guest calls guest_set_pgd() on the top page, and we carefully remap the Switcher text page. But we didn't reset last_host_cpu, so map_switcher_in_guest() thinks the guest's regs and IDT/GDT etc are already mapped.
