drm/amdkfd: Remove svm range validated_once flag

Browse Source 
[ Upstream commit c99b16128082de519975aa147d9da3e40380de67 ]

The validated_once flag is not used after the prefault was removed, The
prefault was needed to ensure validate all system memory pages at least
once before mapping or migrating the range to GPU.
