hal: fix voice call mute during video recording

During a voice call over BT headset, if video recording
is initiated, the voice call gets muted as long as the
recording is active.

A tone is played on both speaker and BT headset to indicate
that video recording has been initiated during which voice call
gets disabled over the BT headset but never gets enabled again.

Avoid disabling of voice call by fixing the conditional check
in check_usecases_capture_codec_backend().
