I spent the time exercising some new fuzzing tools on the ksmbd and smb
code purely because it's something that is simple to set up and test
locally with virtual machines, and in doing so, potentially found some
minor problems for when you have an "untrusted" client.

Here's some fixes for what I happened to notice.  They pass my very
limited testing here, but please don't trust them at all and verify that
I'm not just making this all up before accepting them.

thanks!
