scsi: lpfc: Protect memory leak for NPIV ports sending PLOGI_RJT

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Protect memory leak for NPIV ports sending PLOGI_RJT

There is a potential memory leak in lpfc_ignore_els_cmpl() and
lpfc_els_rsp_reject() that was allocated from NPIV PLOGI_RJT
(lpfc_rcv_plogi()'s login_mbox).

Check if cmdiocb->context_un.mbox was allocated in lpfc_ignore_els_cmpl(),
and then free it back to phba->mbox_mem_pool along with mbox->ctx_buf for
service parameters.

For lpfc_els_rsp_reject() failure, free both the ctx_buf for service
parameters and the login_mbox.
