drm/xe/irq: Don't call pci_free_irq_vectors

For devres managed devices, pci_alloc_irq_vectors is also managed (see
pci_setup_msi_context for reference).
PCI device used by Xe is devres managed (it was enabled with
pcim_enable_device), which means that calls to pci_free_irq_vectors are
redundant and can be safely removed.
