[PATCH kvmtool 1/9] vfio: Fix fd leak in vfio_group_get_for_dev()

[Mostafa Saleh <smostafa@google.com>]

The fd opened to read the iommu_group link of the device is closed
on every path except the one that finds the group already open, so
every device after the first one in a group leaked an fd.
Return through the goto on that path too.
