audio: Do not use StreamSwitcher for StreamPrimary
Since use of StreamSwitcher causes the worker thread to be changed
during connected device change, its use for the primary HAL streams
must be avoided. The reason is that switching of the FMQ reader thread
accompanied with simultaneous writes from two writers: one on the
framework side, another on the HAL side sending the "exit" command,
violates threading assumptions of blocking FMQ and causes spurious
races that eventually make FMQ non-functional.
