MSI: Replace pci_msi_quirk with calls to pci_no_msi()
I don't see any reason why we need pci_msi_quirk, quirk code can just call pci_no_msi() instead. Remove the check of pci_msi_quirk in msi_init(). This is safe as all calls to msi_init() are protected by calls to pci_msi_supported(), which checks pci_msi_enable, which is disabled by pci_no_msi(). The pci_disable_msi routines didn't check pci_msi_quirk, only pci_msi_enable, but as far as I can see that was a bug not a feature.
