A freezable kernel thread can enter frozen state during freezing by
either calling try_to_freeze() or using wait_event_freezable() and its
variants. However, there is no need to use both methods simultaneously.
The freezable wait variants have been used in khugepaged_wait_work()
and khugepaged_alloc_sleep(), so remove this unnecessary
try_to_freeze().
