drm/amdkfd: Skip handle mapping SVM range with no GPU access
If the SVM range has no GPU access nor access-in-place attribute,
validate and map to GPU should skip the range.
Add NULL pointer check if find_first_bit(ctx->bitmap, MAX_GPU_INSTANCE)
returns MAX_GPU_INSTANCE as gpuidx if ctx->bitmap is empty.
