ALSA: isight: add now required waking of DMA context

Since commit 13882a82ee16, upper-layer firewire drivers are required to flush after enqueueing a batch of isochronous buffers.

Actually, snd-isight still worked for me without it but I guess I was just lucky that the controllers (FW643-e, JMB381, XIO2213A) never read up to the current tail of the DMA program.

Dismiss this if you already have something like this in the pipeline.

Sorry for being silent about this, but my original patch is already in Linus' tree.

Indeed, which I would have noticed had I rebased onto -rc4 yet. Thanks,
