kerberos: Calling InitializeSecurityContext without a token buffer is not an error. 

This patch makes Kerberos Authentication Tester work with https and dotnet40.
Apparently that's a dotnet40 quirk that it passes not NULL input buffers
but doesn't mark any of buffers as a token, dotnet20 passes NULL input.

Note, that in order to make version 2.0 applications work (Kerberos
Authentication Tester is such an application) with dotnet40+ one
needs to add to the registry key
[Software\\Microsoft\\.NETFramework]
"OnlyUseLatestCLR"=dword:00000001
