CVE-2021-47045

A flaw was found in the scsi/lpfcIt subsystem of the Linux kernel, where it is possible to call lpfc_issue_els_plogi() passing a did argument for which no matching ndlp is found. A call is then made to lpfc_prep_els_iocb() with a NULL pointer to a lpfc_nodelist structure, resulting in a NULL pointer dereference.
