amdgpu/addrlib: Fix invalid access to m_tileTable

Sometimes client driver passes valid tile info into address library,
in this case, the tile index is computed in function
HwlPostCheckTileIndex instead of CiAddrLib::HwlSetupTileCfg.
We need to call HwlPostCheckTileIndex to calculate the correct tile
index to get tile split bytes for this case.
