[ Upstream commit 8fb7b723924cc9306bc161f45496497aec733904 ]
The kernel thread function ksmbd_conn_handler_loop() invokes the try_to_freeze() in its loop. But all the kernel threads are non-freezable by default. So if we want to make a kernel thread to be freezable, we have to invoke set_freezable() explicitly.
