PCI: Provide pci_free_irq_vectors() stub
473b9f331718 ("rust: pci: fix build failure when CONFIG_PCI_MSI is
disabled") fixed a build error by providing Rust helpers when
CONFIG_PCI_MSI is not set. However the Rust helpers rely on
pci_free_irq_vectors(), which is only available when CONFIG_PCI=y.
When CONFIG_PCI is not set, there is already a stub for
pci_alloc_irq_vectors(). Add a similar stub for pci_free_irq_vectors().
Fixes: 473b9f331718 ("rust: pci: fix build failure when CONFIG_PCI_MSI is disabled")
