Subject: ksmbd: return STATUS_NOT_SUPPORTED on unsupported smb2.0 dialect
From: Namjae Jeon <linkinjeon@xxxxxxxxxx>
commit b53e8cfec30b93c120623232ba27c041b1ef8f1a upstream.
ksmbd returned "Input/output error" when mounting with vers=2.0 to
ksmbd. It should return STATUS_NOT_SUPPORTED on unsupported smb2.0
dialect.
