octeontx2-af: Fix a resource leak in an error handling path in 'cgx_p…

…robe()' If an error occurs after the call to 'pci_alloc_irq_vectors()', we must call 'pci_free_irq_vectors()' in order to avoid a resource leak. The same sequence is already in place in the corresponding 'cgx_remove()' function.
