kvm: qemu: avoid tpr patching when rsp == 0
Early Windows 2003 SMP initialization contains a
mov imm32, r/m32
instruction that is patched by tpr optimization. Problem is rsp, used by
the patched instruction, is zero, so the guest gets a double fault and
dies.
Avoid any patching at all if rsp is zero.
