Don't apply extra AAudio volume ramps

For shared Audio streams, both the exclusive version and the shared version per client will be applying volume changes to the volume ramp.

The fix is to not apply volume changes to shared streams since the exclusive stream will do the ramp.

Bug: 209877538
Test: OboeTester MMAP exclusive/shared
Test: atest AAudioTests
