msi: Fix msi_remove_pci_irq_vectors.
Since msi_remove_pci_irq_vectors is designed to be called during hotplug remove it is actively wrong to query the hardware and expect meaningful results back. To that end remove the pci_find_capability calls. Testing dev->msi_enabled and dev->msix_enabled gives us all of the information we need. Signed-off-by: Eric W.
