Subject: [PATCH] scsi: lpfc: avoid uninitialized variable warning

clang -Wuninitialized incorrectly sees a variable being used without

drivers/scsi/lpfc/lpfc_nvme.c:2102:37: error: variable 'localport' is uninitialized when used here
                lport = (struct lpfc_nvme_lport *)localport->private;
drivers/scsi/lpfc/lpfc_nvme.c:2059:38: note: initialize the variable 'localport' to silence this warning
        struct nvme_fc_local_port *localport;
                                             = NULL
1 error generated.

This is clearly in dead code, as the condition leading up to it is
always false when CONFIG_NVME_FC is disabled, and the variable
is always initialized when nvme_fc_register_localport() got
called successfully.

Change the preprocessor conditional to the equivalent C construct,
which makes the code more readable and gets rid of the warning.
