tasks/fork: Remove unnecessary child->exit_state A zombie task obviously can't fork(), remove the unnecessary initialization of child->exit_state. It is zero anyway after dup_task_struct(). Note: copy_process() is huge and it has a lot of chaotic initializations, probably it makes sense to move them into the new helper called by dup_task_struct().
