subject: MITKRB5-SA-2006-002: svctcp_destroy() can call uninitialized function pointer
component: krb5-libs

Explicitly null out xprt->xp_auth when AUTH_GSSAPI is being used, so
that svctcp_destroy() will not call through an uninitialized function
pointer after code in svc_auth_gssapi.c has destroyed expired state
structures.  We can't unconditionally null it because the RPCSEC_GSS
implementation needs it to retrieve state.
