I suppose this is in 'lpfc_sli_process_sol_iocb()'. It's return 
value doesn't get handled either:

                case LPFC_SOL_IOCB:                                              
                        spin_unlock_irqrestore(&phba->hbalock, iflag);           
                        rc = lpfc_sli_process_sol_iocb(phba, pring, saveq);      
                        spin_lock_irqsave(&phba->hbalock, iflag);                
                        break;                                                   
[...]                                                       
                }                                                                
                                                                                 
                if (free_saveq) {                                                
                        list_for_each_entry_safe(rspiocbp, next_iocb,            
                                                 &saveq->list, list) {           
                                list_del_init(&rspiocbp->list);                  
                                __lpfc_sli_release_iocbq(phba, rspiocbp);        
                        }                                                        
                        __lpfc_sli_release_iocbq(phba, saveq);                   
                }                                                                
                rspiocbp = NULL;                                                 
        }                                                                        
        spin_unlock_irqrestore(&phba->hbalock, iflag);                           
        return rspiocbp;
