ALSA: hda/realtek - Don't detect LO jack when identical with HP
The spec->autocfg.line_out_pins[] may contain the same pins as hp_pins[] depending on the configuration. When they are identical, detecting the line_jack_present flag screws up the auto-mute because alc_line_automute() is called unconditionally at initialization while it won't be triggered by unsol events, thus the old line_jack_present flag is kept for the whole run. For fixing this buggy behavior, the driver needs to check whether the line-outs are really individual, and skip if same as headphone jacks.
