Use correct AUTH when calling RPCSEC_GSS_DESTROY.
Use correct AUTH when calling RPCSEC_GSS_DESTROY.

When using multiple AUTHs per client connection, calling
AUTH_DESTROY(auth) may result in 'cl_auth' being set to something other
than 'auth'.

Avoid this by saving and restoring 'cl_auth' across the
RPCSEC_GSS_DESTROY clnt_call().
