Subject: Failure to recreate virtual functions

Hi Lu Baolu,
Our mlx5 driver fails to recreate VFs when cmdline includes
"intel_iommu=on iommu=pt" after recent merge of patch set "iommu/vt-d:
Delegate DMA domain to generic iommu". I've bisected the failure to
patch b7297783c2bb ("iommu/vt-d: Remove duplicated code for device
hotplug"). Here is the dmesg log for following case: enable switchdev
mode, set number of VFs to 0, then set it back to any value
>0.
