The lpfc_cmpl_ct_disc_fdmi routine has incorrect logic that treats an FDMI completion with error LOCAL_REJECT/SLI_ABORTED as a success status. Under the erroneous assumption of successful completion, the routine proceeds to issue follow up FDMI commands, which may never complete if the HBA is in an errata state as indicated by the errored completion status. Fix by freeing FDMI cmd resources and early return when the LPFC_SLI_ACTIVE flag is not set and a LOCAL_REJECT/SLI_ABORTED or SLI_DOWN status is received.
