audio: Fix logic for resuming when the device is in use.

audio_[r/p]mixer_start should never be called when the device is
marked busy.

Resolves a panic on resume when audio is playing, PR kern/55301

audio: remove comment that is no longer valid

audio: Only restart recording mixer on resume if it's already been started

Fix suspend/resume.
- Revert temporary usage of sc_[pr]busy during suspend.  These indicate
  whether the mixer needs to be restarted or not.
- Avoid timeout error when about to suspend.
