audioserver: Use timed lock instead of bouncing for dumps

The technique of bouncing lock attempts does not work well
in the case when another lock has higher priority and acquires
the lock frequently. Timed lock works better in this case
because the acquiring thread is then put in a queue and gets
the lock as soon as another thread releases it. The wait time
in the worst case (deadlock) is the same.

Bug: 118842894
Test: Run VOICE_COMMUNICATION capture + AEC effect, dump audioflinger
