LU-8795 gss: Prevent callout truncation with non-root users

The SK changes included an additional svc_type field in the callout
which was initialized to the '0'.  Since the defaulted value is
not changed prior to callout for non-root users this breaks those
kerberos users.  SK is not affected because all users share the same
key context which is limited to the root user.
