libaudiohal@aidl: Fix setDevicePortConnectedState

`setDevicePortConnectedState` stores iterators on `mPorts`
and then calls `resetUnusedPortConfigs` which can also
invalidate `mPorts`. This becomes more obvious after
renaming `resetUnusedPortConfigs` to `resetUnusedPortConfigsAndPorts`.
This call needs to be moved to the beginning of
`setDevicePortConnectedState` so that iterators on `mPorts`
remain valid.
