CVE-2021-47045

It is possible to call lpfcissueelsplogi() passing a did for which no matching ndlp is found. A call is then made to lpfcprepelsiocb() with a null pointer to a lpfc_nodelist structure resulting in a null pointer dereference.

Fix by returning an error status if no valid ndlp is found. Fix up comments regarding ndlp reference counting.
