Fix sort-out of non-existing devices in namehint

Browse source 
get_dev_name() checks wrongly the device_output, and it doesn't check
properly the case when only device is set and device_input and output
are unset.  This resulted in listing of non-existing HDMI device, for
example.  The patch fixes both issues.
