When used in linux-user mode, tlb_vaddr_to_host(..., addr, ...))
should return "g2h(addr)", but instead it returns "g2h(vaddr)".
As "vaddr" is "typedef uint64_t", the result of "g2h(vaddr)" is
"((void *)((unsigned long)(target_ulong)(uint64_t) + guest_base))".
This bug has been found trying to run "ls" with qemu-ppc.
Fixes: "c9f82d0 ppc: Speed up dcbz"
