nfsd4: fix security flavor of NFSv4.0 callback
Commit d5497fc693a446ce9100fcf4117c3f795ddfd0d2 "nfsd4: move rq_flavor into svc_cred" forgot to remove cl_flavor from the client, leaving two places (cl_flavor and cl_cred.cr_flavor) for the flavor to be stored. After that patch, the latter was the one that was updated, but the former was the one that the callback used. Symptoms were a long delay on utime(). This is because the utime() generated a setattr which recalled a delegation, but the cb_recall was ignored by the client because it had the wrong security flavor.
