[PATCH] drm/amdgpu: Disable GPU reset on SRIOV before remove pci.

[Gavin Wan]

  The change "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 VF FLR of SRIOV
  sequence is wrong while removing PCI device.
