scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc()
[ Upstream commit 2ae917d4bcab80ab304b774d492e2fcd6c52c06b ]
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.
