Subject[PATCH] wait_event_freezekillable: use freezer_do_not_count/freezer_count
fake_signal_wake_up() should not wake up the TASK_KILLABLE tasks,
we are going to fix this. This means that wait_event_freezekillable()
can't rely on wakeup from freezer. Reimplement it using
freezer_do_not_count/freezer_count. This is not really nice, just
a simple fix for now.
