drm/amd: Fix unbind/rebind for VCN 4.0.5
commit 93a01629c8bfd30906c76921ec986802d76920c6 upstream.
Unbinding amdgpu has no problems, but binding it again leads to an
error of sysfs file already existing. This is because it wasn't
actually cleaned up on unbind. Add the missing cleanup step.
Fixes: 547aad32edac ("drm/amdgpu: add VCN4 ip block support")
