[SCSI] lpfc: Fix NPIV compile problem

drivers/scsi/lpfc/lpfc_init.c: In function 'lpfc_create_port':
drivers/scsi/lpfc/lpfc_init.c:1573: error: 'struct kobject' has no member named 'dentry'

Just remove the if check on this ... lpfc shouldn't be poking around
in kobject structures.

drivers/scsi/lpfc/lpfc_init.c: In function 'lpfc_pci_probe_one':
drivers/scsi/lpfc/lpfc_init.c:1723: warning: unused variable 'retval'

And remove the unused variable.
