scsi: lpfc: Free phba irq in lpfc_sli4_enable_msi() when pci_irq_vector() fails

Fix smatch warning regarding missed calls to free_irq().  Free the phba IRQ
in the failed pci_irq_vector cases.

lpfc_init.c: lpfc_sli4_enable_msi() warn: 'phba->pcidev->irq' from
             request_irq() not released.
