ksmbd: close accepted socket when per-IP limit rejects connection

Vulnerability Description

In the Linux kernel, the following vulnerability has been resolved: ksmbd: close accepted socket when per-IP limit rejects connection When the per-IP connection limit is exceeded in ksmbd_kthread_fn(), the code sets ret = -EAGAIN and continues the accept loop without closing the just-accepted socket. That leaks one socket per rejected attempt from a single IP and enables a trivial remote DoS. Release client_sk before continuing. This bug was found with ZeroPath.
