drm/amdgpu: don't attach the tlb fence for SI
SI hardware doesn't support pasids, user mode queues, or
KIQ/MES so there is no need for this. Doing so results in
a segfault as these callbacks are non-existent for SI.
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4744
Fixes: f3854e04b708 ("drm/amdgpu: attach tlb fence to the PTs update")
