Hi all, after reviewing various patches from Pan Nengyuan fix ppc-e500
fdt memleaks, I search for related content and found Paolo Bonzini's
similarly patchs. (sorry, this description is missing here because of this patch format.)

>We should free it after cpu_physical_memory_write().Otherwise,
>if we repeatedly call 'system_reset',it will repeatedly load fdt, so there are
>many memleaks.
