[Qemu-trivial] [PATCH] migration: reorder code to make it symmetric

[Wei Yang <richard.weiyang@gmail.com>]

In qemu_savevm_state_complete_precopy(), it iterates on each device to add
a json object and transfer related status to destination, while the order
of the last two steps could be refined.

Current order:

    json_start_object()
    	save_section_header()
    	vmstate_save()
    json_end_object()
    	save_section_footer()

After the change:

    json_start_object()
    	save_section_header()
    	vmstate_save()
    	save_section_footer()
    json_end_object()

This patch reorder the code to to make it symmetric. No functional change.
