make sure that kernel_thread() callbacks call do_exit() themselves
Most of them never returned anyway - only two functions had to be changed. That allows to simplify their callers a whole lot. Note that this does *not* apply to kthread_run() callbacks - all of those had been called from the same kernel_thread() callback, which did do_exit() already. This is strictly about very few low-level kernel_thread() callbacks (there are only 6 of those, mostly as part of kthread.h and kmod.h exported mechanisms, plus kernel_init() itself).
