Set cred->user_ns in key_replace_session_keyring
Since this cred was not created with copy_creds(), it needs to get
initialized. Otherwise use of syscall(__NR_keyctl, KEYCTL_SESSION_TO_PARENT);
can lead to a NULL deref. Thanks to Robert for finding this.
But introduced by commit 47a150edc2a ("Cache user_ns in struct cred").
