cpu/x86/mp_init: Allow stub sizes larger than the save state size
The permanent handler module argument 'save_state_size' now holds the
meaning of the real save state size which is then substracted from the
CPUs save state 'top' to get the save state base.
TESTED with qemu Q35 on x86_64 where the stub size exceeds the AMD64
save state size.
