PCI/MSI: Set pci_dev::msi[x]_enabled early
There are quite some places which retrieve the first MSI descriptor to
evaluate whether the setup is for MSI or MSI-X. That's required because
pci_dev::msi[x]_enabled is only set when the setup completed successfully.
There is no real reason why msi[x]_enabled can't be set at the beginning of
the setup sequence and cleared in case of a failure.
Implement that so the MSI descriptor evaluations can be converted to simple
property queries.
