The change of the commit <f5c7e7797060> ("Adjust removal control
flow for smu v13_0_2") brought a bug on SRIOV envrionment. It
caused unloading amdgpu failed on Guest VM. The reason is that
the VF FLR was requested while unloading amdgpu driver, but the
VF FLR of SRIOV sequence is wrong while removing PCI device.
