In hibernation, all the blocks are powered off expect the HIB block itself. The HIB block signals the PMU to turn off the chip and turn on again after exiting from hibernation. Upon startup the device goes through cold boot sequence. So it is not necessary to bring network down and call wiced deinit but it would be advisable to make sure your work is done before entering hibernation because no state is saved during hibernation other than the logic state of HIB block.
