Revert "AudioPolicyManager: fix closure of output supporting more than on device"

This reverts commit d7a5f2de.
It introduced a regression on patch / port id alignement between
java and native layer.
The patch involving the output was neither deleted nor recreated.
It still involves a device port id that was disconnected, thus does
not exist anymore.
Java side layer will not identify this port (match on id).

The resolution of the issue (particurily for the primary output, since
it may be removed and not assigned until one or more device reachable
by the primary is reconnected) shall reconsider the output (either closing
or rerouting) rather than keeping it blindly.
