__group_complete_signal: eliminate unneeded wakeup of ->group_exit_task

Cleanup.  __group_complete_signal() wakes up ->group_exit_task twice.  The
second wakeup's state includes TASK_UNINTERRUPTIBLE, which is not very
appropriate.

Change the code to pass the "correct" argument to signal_wake_up() and kill
now unneeded wake_up_process().
