nfsd: update callback done processing
Instead of having the convention where individual nfsd4_callback_ops->done
operations return -1 to indicate the callback path is down, move the check
to nfsd4_cb_done. Only mark the callback path down on transport-level
errors, not NFS-level errors.
The existing logic causes the server to set SEQ4_STATUS_CB_PATH_DOWN
just because the client returned an error to a CB_RECALL for a
delegation that the client had already done a FREE_STATEID for. But
clearly that error doesn't mean that there's anything wrong with the
backchannel.
Additionally, handle NFS4ERR_DELAY in nfsd4_cb_recall_done. The client
returns NFS4ERR_DELAY if it is already in the process of returning the
delegation.
