Namjae Jeon 33a9657d67 ksmbd: limit pdu length size according to connection status
commit 62c487b53a upstream.

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.
