scsi: lpfc: Fix backport of faf5a744f4f8 ("scsi: lpfc: avoid uninitialized variable warning")
Prior to commit 4c47efc140fa ("scsi: lpfc: Move SCSI and NVME Stats to hardware queue structures") upstream, we allocated a cstat structure in lpfc_nvme_create_localport. When commit faf5a744f4f8 ("scsi: lpfc: avoid uninitialized variable warning") was backported, it was placed after the allocation so we leaked memory whenever this function was called and that conditional was true (so whenever CONFIG_NVME_FC is disabled). Move the IS_ENABLED if statement above the allocation since it is not needed when the condition is true.
