When a vCPU migrates to a different host CPU, the new CPU may retain stale VS-stage TLB entries (GVA → GPA) left by a previous run of the same guest. Issue an HFENCE.VVMA (all ASIDs, all addresses) inside kvm_riscv_mmu_update_hgatp() whenever the vCPU is loaded on a CPU different from the one it last exited on.
