scsi: lpfc: Fix lpfc_force_rscn ndlp kref imbalance
Issuing lpfc_force_rscn twice results in an ndlp kref use-after-free call trace. A prior patch reworked the get/put handling by ensuring nlp_get was done before WQE submission and a put was done in the completion path. Unfortunately, the issue_els_rscn path had a piece of legacy code that did a nlp_put, causing an imbalance on the ref counts. Fixed by removing the unnecessary legacy code snippet.
