This change is safe since it doesn't change the vmstate layout so that
there's no need for bumping up the version.
But I still have the question as the comment in v1 [*]. User doesn't
have any way to modify the number of timers, why not just replace this
vmstate field with "VMSTATE_UNUSED_V(2, 1)"?
Or do you think we should keep the status quo for the future use, even
if these properties have not been modified yet?
