BUG=109959
TEST=none
(covered by existing tests and tested locally with built-in audio,
 Metric Halo 2882, and Stanton FinalScratch Firewire devices to
 verify that crashes are fixed)

Incidentally, the stream latency was always reported as zero on the devices I tested,
so removing this code should have no practical impact.
