ALSA: Call snd_pcm_drain() on suspend
The ALSA plugin previously didn't suspend the ALSA device when the
::suspend() method is called. This results in underrun errors when
it's resumed.
In ALSA, stopping a pcm doesn't close it, so the ALSA stop/start
functions map to the QAudioInput suspend/resume functions.
