If we get a bad-stateid-type of error when we send OPEN with delegate_cur to return currently held delegation, we shouldn't be trying to reclaim locks associated with that delegation state_id because we don't have an open_stateid to be used for the LOCK operation. Thus, we should return an error from the nfs4_open_delegation_recall() in that case. Furthermore, if an error occurs the delegation code will call nfs_abort_delegation_return() which sets again the NFS4CLNT_DELEGRETURN flags in the state and it leads the state manager to into an infinite loop for trying to reclaim the delegated state.
