The call to lpfc_sli4_resume_rpi in lpfc_rcv_padisc may return an
unsuccessful status.  In such cases, the elsiocb is not issued, the
completion is not called, and thus the elsiocb resource is leaked.

Check return value after calling lpfc_sli4_resume_rpi and conditionally
release the elsiocb resource.
