hal: Fix ANR if In-Call recording is started at end of voice call
Sometimes ANR is observed, if In-call recording is started at the
end of voice call.
Incorrect use case "afe-proxy-record" is being picked up in this
case as voice call is not active by the time audio HAL starts
the input stream, thus resulting in pcm device open failures.
Fix this by rejecting start input request if voice call is not
active by the time input is started.
