ALSA: hda/realtek: Remove specific patch for Dell Precision 3260

Unfortunately, the tester gave a weak feedback (working/non-working) for
this case. After the double confirmation, this change is not really required.
The standard code with alc269_fallback_pin_fixup_tbl should work on this
hardware.
