Alex Williamson 9a92c5091a vfio-pci: Enable device before attempting reset ... Devices making use of PM reset are getting incorrectly identified as not supporting reset because pci_pm_reset() fails unless the device is in D0 power state. When first attached to vfio_pci devices are typically in an unknown power state. We can fix this by explicitly setting the power state or simply calling pci_enable_device() before attempting a pci_reset_function(). We need to enable the device anyway, so move this up in our vfio_pci_enable() function, which also simplifies the error path a bit. Note that pci_disable_device() does not explicitly set the power state, so there's no need to re-order vfio_pci_disable().
