PCI: read current power state at enable time
When we enable a PCI device, we avoid doing a lot of the initial setup work if the device's enable count is non-zero. If we don't fetch the power state though, we may later fail to set up MSI due to the unknown status. So pick it up before we short circuit the rest due to a pre-existing enable or mismatched enable/disable pair (as happens with VGA devices, which are special in a special way).
