d3d11h264dec: Keep track of actually configured DPB size

Browse source 
... instead of the largest we ever seen.
Note that d3d11h264dec element holds previously configured DPB size
for later decoder object re-open decision.

This is to fix below case:
1) Initial SPS, required DPB size is 6
  - decoder object is opened with DPB size 6
  - max_dpb_size is now 6
2) SPS update with resolution change, required DPB size is 1
  - decoder object is re-opened with DPB size 1
  - max_dpb_size should be updated to 1, but it didn't happen (BUG)
3) SPS update without resolution change, only required DPB size is updated to 6
  - decoder object should be re-opened but didn't happen
    because we didn't update max_dpb_size at 2).
