Bug description:
  [Impact]
  When a BT headset is connected Realtek BT USB controller, HFP profile can't 
play or record sound when mSBC codec is used.

  [Fix]
  At Linux kernel side, add a Realtek specific quirk to support mSBC.

  At PulseAudio side, send more data frames until the connected device
  sends response.

  [Test]
  Connect different headsets to the said controller, HFP can play and record 
sounds now.
  Also verified A2DP profile is unaffected.

  [Where problems could occur]
  The kernel part is Realtek specific, so the regression risk is very limited.

  The pulseaudio side only affects HFP profile, since the codeflow only
  changes when a mic is present.
