audiod: Set the audio format restart barrier also when closing the receiver.

When the current audio file changes, it may happen that para_audiod's receiver
detects the EOF condition before the status has been updated to reflect the file
change. In this case, para_audiod might restart the old receiver even if a
different audio format is about to be streamed next.

This patch adds a per audio format 200ms delay which starts at receiver close time.
During this time interval the receiver for this audio format will not be started again.
