Use the correct variable in the DCHECK
A patch changed how a value was retrieved to use a different variable,

introduced in the following CL:
https://codereview.chromium.org/1479883002
TEST=Load youtube.com/tv, start a video and switch to a suggested video.
The above steps will trigger the dcheck in content_shell.
