Re: SMB3.11 security fixes

Two nits

1, maybe change the conditional to check for >= 3.1.1 instead of == 3.1.1
(since it is unlikely this requirement will revert back once we have
later versions of smb3.)

2, 3.2.4.1.1 says signing must be used IF the session has
EncryptData==False, but that is not what the code checks for.
It checks for is !guest user. Is that the right check?
(guest can never have encrypted sessions  but !guest can have
not-encrypted sessions.)
