At the Qemu initialization, we call the cpu_synchronize_all_post_init()
to synchronize All CPU states to KVM in the ./vl.c::main().

Currently, it is called before we initialize the CPUs, which is created
by "-device" command and parsed by generic devices initialization, So,
these CPUs may be ignored to synchronize.

The patch moves the cpu_synchronize_all_post_init func after generic
devices initialization to make sure that all the CPUs can be included.
