Revert of Simplify LoadableTextTrack::trackElementIndex (patchset #1 id:1 of https://codereview.chromium.org/1980013002/ )
Reason for revert:
Seems "WebKit Win Builder (dbg)" didn't approve:
e:\b\build\slave\webkit-win-latest-dbg\build\src\third_party\webkit\source\core\html\track\loadabletexttrack.cpp(70) : warning C4706: assignment within conditional expression
Original issue's description:
> Simplify LoadableTextTrack::trackElementIndex
>
> Count preceding sibling <track> elements in a more straight-forward way.
>
> Also clean-up null-checks of m_trackElement while here (should be non-
> null on construction and then keeps a strong reference.)
