SMB3: Fix length checking of SMB3.11 negotiate request
The length checking for SMB3.11 negotiate request includes "negotiate contexts" which caused a buffer validation problem and a confusing warning message on SMB3.11 mount e.g.: SMB2 server sent bad RFC1001 len 236 not 170 Fix the length checking for SMB3.11 negotiate to account for the new negotiate context so that we don't log a warning on SMB3.11 mount by default but do log warnings if lengths returned by the server are incorrect.
