[SCSI] lpfc 8.3.19: Fix critical errors and crashes

Fix critical errors and crashes

- Replace LOF_SECURITY with LOG_SECURITY
- When calculating diag test memory size, use full size with header.
- Return LS_RJT with status=UNSUPPORTED on unrecognized ELS's
- Correct NULL pointer dereference when lpfc_create_vport_work_array()
  returns NULL.
- Added code to handle CVL when port is in LPFC_VPORT_FAILED state.
- In lpfc_do_scr_ns_plogi, check the nodelist for FDMI_DID and reuse
  the resource.
- Check for generic request 64 and calculate the sgl offset for the request
  and reply sgls, also calculate the xmit length using only the request bde.
