thinkpad-acpi: kill hotkey_thread_mutex
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().
