[PATCH 3/6] msi: Fix msi_remove_pci_irq_vectors.

[Eric W. Biederman]

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.
