[Qemu-devel] [PULL 16/19] vfio/pci: Remove vfio_populate_device returned value

[Alex Williamson <alex.williamson@redhat.com>]

From: Eric Auger <eric.auger@redhat.com>

The returned value (either -errno or -1) is not used anymore by the caller,
vfio_realize, since the error now is stored in the error object. So let's
remove it.
