Subject: audio: Update anchor time for offload playback post resume

 -AV sync is lost after multiple pasue/resume operatins.

 -Renderer does not update anchor time post resume and it may
  lead to AV sync loss after multiple pause/resume in offload
  playback case.

 -Get renderer position and update anchor time post resume
  for offload audio
