The server sunrpc code should take a reference on the relevant module before
calling any authentication code.

Also, it looks to me like the table of authops needs some locking.

Finally, gss_svc_init wasn't checking the status of svc_auth_register, and
gss_svc_shutdown wasn't calling svc_auth_unregister.
