x86/boot/64: Push correct start_cpu() return address
start_cpu() pushes a text address on the stack so that stack traces from
idle tasks will show start_cpu() at the end. But it currently shows the
wrong function offset. It's more correct to show the address
immediately after the 'lretq' instruction.
