[PATCH] vivid: Fix V4L2_FIELD_ALTERNATE new frame check

[Nicolas Dufresne]

The vivid driver will overlay stream time on generated frames. Though,
in interlacing mode V4L2_FIELD_ALTERNATE, each field is separate and
must have the same time to ensure proper render. Though, this time was
only updated every 2 frames as the code was checking against the wrong
counter (frame counter rather then field counter).
