scsi: lpfc: code cleanups in NVME initiator discovery

This patch addresses the smatch issues identified by Dan Carpenter
in http://www.spinics.net/lists/linux-scsi/msg105665.html

The issues are:

drivers/scsi/lpfc/lpfc_ct.c:943 lpfc_cmpl_ct_cmd_gft_id()
error: we previously assumed 'ndlp' could be null (see line 928)

Action: moved under if check

drivers/scsi/lpfc/lpfc_nvmet.c:1694 lpfc_nvmet_unsol_issue_abort()
error: we previously assumed 'ndlp' could be null (see line 1690)

Action: conditionalized arg in printf stmt

drivers/scsi/lpfc/lpfc_nvmet.c:1792 lpfc_nvmet_sol_fcp_issue_abort()
error: we previously assumed 'ndlp' could be null (see line 1788)

Action: conditionalized arg in printf stmt
