Fix data fetcher for light stop correctly on windows.

Fix data fetcher for light stop correctly on windows.

SetBufferAvailableState was from called DataFetcherSharedMemory::Stop for all
cases including TYPE_LIGHT, but for light, we are not using it as
we are using SetLightBuffer(light_buffer_, -1);

Hi Tim,
while adding the layout tests in https://codereview.chromium.org/490773003/, I
saw that the win_blink_rel was crashing, I don't have a windows build setup
right now, but i think this is the reason for the crash. PTAL.

lgtm, I assume it fails on NOTREACHED in SetBufferAvailableState. Could you
create a separate bug for this with a link to the failing bot? thanks.
