pcm core: fixed spurious XRUN issues

This fixes the numerous XRUN issues seen on some cards.
The trick is to set the buffer_size & period size in
hw parameters. These ones are calculated from an expected
maximum latency.
Also, the writei is done in a loop to be robust to overruns
and partial writes.
