scsi: lpfc: Fix backport of faf5a744f4 ("scsi: lpfc: avoid uninitialized variable warning")

Browse Source 
Prior to commit 4c47efc140 ("scsi: lpfc: Move SCSI and NVME Stats to
hardware queue structures") upstream, we allocated a cstat structure in
lpfc_nvme_create_localport. When commit faf5a744f4 ("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.
