ksmbd: fix null pointer dereference error in generate_encryptionkey
commit 9b493ab6f35178afd8d619800df9071992f715de upstream.
If client send two session setups with krb5 authenticate to ksmbd,
null pointer dereference error in generate_encryptionkey could happen.
sess->Preauth_HashValue is set to NULL if session is valid.
So this patch skip generate encryption key if session is valid.
