AudioPolicyManager: Stop the descriptor when closing its output

This fixes the case when the SwAudioOutputDescriptor is part of
duplicated output. In this case, APM::closeOutput finds the
duplicated output, deactivates all the clients for all outputs,
then calls 'close' on the descriptor. Since there are no active
clients, closing the descriptor does not stop it, leaving
pending 'active count' in the profile.
