drm/amdgpu: revert "Don't change preferred domian when fallback GTT v6"
This reverts commit 7d1ca1325260a9e9329b10a21e3692e6f188936f.
Makes fallback handling to complicated. This is just a feature for the
GEM interface and shouldn't leak into the core BO create function.
The intended change to preserve the preferred domains is implemented in
a follow up patch.
