Fix use of gw_get_shared_session_auth_info

Browse Source 
If the client DCB of the session was passed into the function, it was
possible that the session pointer for it was already set to null. The
session pointer of an open DCB is never null but a client DCB's session
pointer can be null if accessed via the MXS_SESSION object.
