avcodec/hevcdec: constrained intra predict, do not check top left IS_INTRA if it's not available
fix ticket: 8932
For poc 2, we have tile boundary at x = 640.
When we predict cu(640,912),the top left pixel is not avaliable to the cu.
So, we can not check it's intra or not. We need set top[-1] = top[0] directly.
see 8.4.4.2.1 for details
