fs/proc/task_mmu.c: shift "priv->task = NULL" from m_start() to m_stop()
1. There is no reason to reset ->tail_vma in m_start(), if we return
IS_ERR_OR_NULL() it won't be used.
2. m_start() also clears priv->task to ensure that m_stop() won't use
the stale pointer if we fail before get_task_struct(). But this is
ugly and confusing, move this initialization in m_stop().
