mtd: nand: make suspend work if device is accessed by kernel threads.
Since all userspace threads are frozen at the time the nand_suspend is called, they aren't inside any nand function. We don't call try_to_freeze in nand ether. Thus the only user that can be inside the nand functions is an non freezeable kernel thread. Thus we can safely wait for it to finish.
