drm/amdgpu: move amdgpu_virt_release_full_gpu to fini_early stage
[ Upstream commit 6effad8abe0ba4db3d9c58ed585127858a990f35 ]
adev->rmmio is set to be NULL in amdgpu_device_unmap_mmio to prevent
access after pci_remove, however, in SRIOV case, amdgpu_virt_release_full_gpu
will still use adev->rmmio for access after amdgpu_device_unmap_mmio.
The patch is to move such SRIOV calling earlier to fini_early stage.
Fixes: 07775fc13878 ("drm/amdgpu: Unmap all MMIO mappings")
