commit 6d5e8a2d5661df3ad82f54b455d6159e7e8fd3a7
Author: Ted Meyer <tmathmeyer@chromium.org>

Fix race condition:

There is a race condition between AudioRenderer::Reinitialize and

audio_clock_ to null. Sometimes webmediaplayerimpl can request a
timestamp from the pipeline->renderer->audio_renderer which could race
with an ongoing track switch doing a reinitialize.

AudioRenderer: :CurrentMediaTime where reinitialize was setting
