SUNRPC: Don't attempt to destroy expired RPCSEC_GSS credentials..
..and always destroy using a 'soft' RPC call. Destroying GSS credentials isn't mandatory; the server can always cope with a few credentials not getting destroyed in a timely fashion. This actually fixes a hang situation. Basically, some servers will decide that the client is crazy if it tries to destroy an RPC context for which they have sent an RPCSEC_GSS_CREDPROBLEM, and so will refuse to talk to it for a while. The regression therefor probably was introduced by commit 0df7fb74fbb709591301871a38aac7735a1d6583. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
