This patch revert commit 8f7d9ec. In function vtophys_iommu_init(), we
can use `dev->drvier` in RTE_DEV_FOREACH() loop to count number of devices
probed by device driver using vfio APIs, or we will count all the PCI devices
that bind to vfio-pci driver, only the probed device's IOMMU group is added
to vfio container.
The original implementation is correct to count `g_vfio.device_ref` in
vtophys_pci_device_added(), we don't need to count it in
vtophys_iommu_device_event() callback.
Fix issue #2086.
