audiopolicy: Fix after commit 11d301045991dd66bf3f64ba510e069b7c09fedb

The change ag/5874343 switched to DeviceVector usage instead of
audio_devices_t. In AudioPolicyManager::setOutputDevices, one of
the conditions comparing a device to AUDIO_DEVICE_NONE had been
inverted.

This was resulting in resetting of default patches during
a call to 'setForceUse' function.

Test: audiopolicy_tests
