This is v2 of the patch sent yesterday. In addition to including
the missing vfio bits, I split it in two parts: one introducing
instance_finalize (patch 2), and the second making the freeing of BARs
RCU-friendly (patch 3).
With these two changes I found the error path logic a bit hard
to follow. So I preceded it with patch 1, which tries to make things
a little bit clearer, at least to me.
VFIO is probably the device that requires the largest changes, due to
the complex, highly data-driven initialization sequence. No other device
can use so many dynamic data structures, because their configuration is
obviously not as variable as for PCI pass-through.

Paolo Bonzini (3):
vfio: cleanup vfio_get_device error path, remove vfio_populate_device callback
vfio: free dynamically-allocated data in instance_finalize
vfio: unmap and free BAR data in instance_finalize
