ksmbd: limit pdu length size according to connection status
Stream protocol length will never be larger than 16KB until session setup. After session setup, the size of requests will not be larger than 16KB + SMB2 MAX WRITE size. This patch limits these invalidly oversized requests and closes the connection immediately.
