Do one shot cpu sync at qemu_savevm_state_complete_precopy_non_iterable(),

Note that in the context of qemu_savevm_state_complete_precopy(), this

Postcopy invokes qemu_savevm_state_complete_precopy() twice for a long
time, and that caused way too much confusions. Let's clean this up and
make postcopy easier to read.
It's actually fairly straightforward: postcopy starts with saving
non-postcopiable iterables, then later it

This paves way for some follow up patch to modify migration states at the

Precopy uses unlimited bandwidth always during switchover, it makes sense
because this is so critical and no one would like to throttle bandwidth

OTOH, postcopy surprisingly didn't do that. There's one line that in the
