drm/amd: Don't try to enable secure display TA multiple times

Browse Source 
If the securedisplay TA failed to load the first time, it's unlikely
to work again after a suspend/resume cycle or reset cycle and it appears
to be causing problems in futher attempts.

Fixes: e42dfa66d5 ("drm/amdgpu: Add secure display TA load for Renoir")
