hotkey_kthread() does try_to_freeze() under hotkey_thread_mutex.
We can simply kill this mutex, hotkey_poll_stop_sync() does not need
to serialize with hotkey_kthread(). When kthread_stop() returns the
thread is already dead, it called do_exit()->complete_vfork_done().

hotkey_kthread() does try_to_freeze() under hotkey_thread_mutex.
We can simply kill this mutex, hotkey_poll_stop_sync() does not need
to serialize with hotkey_kthread(). When kthread_stop() returns the
thread is already dead, it called do_exit()-complete_vfork_done().
