Octeontx2-af: Fix pci_alloc_irq_vectors() return value check

In cgx_probe() when pci_alloc_irq_vectors() fails the error value will
be negative and that check is sufficient.

	err = pci_alloc_irq_vectors(pdev, nvec, nvec, PCI_IRQ_MSIX);
        if (err < 0 || err != nvec) {
        	...
	}

When pci_alloc_irq_vectors() fail to allocate nvec number of vectors,
-ENOSPC is returned, so it would be safe to remove the check that
compares err with nvec.
