ksmbd: Add missing set_freezable() for freezable kthread

From: Kevin Hao <haokexin@gmail.com>

[ 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.
