Oleg Nesterov beed61068f kernel/fork.c:copy_process(): unify CLONE_THREAD-or-thread_group_leader code ...

commit 80628ca06c upstream.

Cleanup and preparation for the next changes.

Move the "if (clone_flags & CLONE_THREAD)" code down under "if
(likely(p->pid))" and turn it into into the "else" branch.  This makes the
process/thread initialization more symmetrical and removes one check.
