ALSA: hda - Fix multi-headphone handling for Realtek codecs



When multiple headphone pins are defined without line-out pins, the
driver takes them as primary outputs.  But it forgot to set line_out_type
to HP by assuming there is some rest of HP pins.  This results in some
mis-handling of these pins for Realtek codec parser.  It takes as if
these are pure line-out jacks.
