[PATCH v3 3/3] drm/amdgpu: remove useless enable/disable of ttm buffer funcs

[Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com>]

amdgpu_ttm_disable_buffer_funcs and amdgpu_ttm_enable_buffer_funcs should
each only be called once per amdgpu_device: at startup and teardown.

Therefore the other calls are redundant and can be safely dropped.
