Call traces are being seen that result from a nodelist structure ref counting error. They are typically seen after transmission of an LS_RJT ELS response. Aged code in lpfc_cmpl_els_rsp() calls lpfc_nlp_not_used() which, if the ndlp reference count is exactly 1, will decrement the reference count. Previously lpfc_nlp_put() was within lpfc_els_free_iocb(), and the 'put' within the free would only be invoked if cmdiocb->context1 was not NULL. Since the nodelist structure reference count is decremented when exiting lpfc_cmpl_els_rsp() the lpfc_nlp_not_used() calls are no longer required. Calling them is causing the reference count issue. Fix by removing the lpfc_nlp_not_used() calls.
