Tweak identifiers after r635967.

DowncastTraits<RemoteFrame>::AllowFrom may be given a non-RemoteFrame
as its argument (its job is to determine that), so the parameter is
properly called "frame".

DowncastTraits<RootFrameViewport>::AllowFrom used to be a macro and
so escaped the style rewrite that should have given it a hacker_case
name, "scrollable_area".
