Fix the pesky write corruption bug in 4bit mode.
On tx underruns, a write is aborted early, leaving the dma channel active.
We didn't explicitly disable it, so there were still 4 words in the dma
controller fifo, corrupting the retried write.
To chase this bug I added verify after write, if no one sees write errors in
the next week or so this can be removed.
