Remove start_kernel()->mm_init_owner(&init_mm, &init_task).
This doesn't really hurt but unnecessary and misleading. init_task
is the "swapper" thread == current, its ->mm is always NULL. And
init_mm can only be used as ->active_mm, not as ->mm.
mm_init_owner() has a single caller with this patch, perhaps it
should die. mm_init() can initialize ->owner under #ifdef.
