This patch fixes a regression introduced by a patch I sent in Nov
That patch got ack but not formally merged to ubuntu kernel yet, I generated
this patch on the master-next-backlog branch of ubuntu-bionic, so for
B/C/D/unstable kernel, please apply the patch of the (2018-November/096882.html)
first, then apply this patch.

The mute led can't work on several lenovo laptop models after applying the
patch of #1805079, this is a regression introduced by that patch.

chanin the ALC269_FIXUP_THINKPAD_ACPI, this will make the led work again.

[Test Case]
press F1 and F4, the mute led and micmute led work well.

[Regression Potential]
Very low, this patch is specific to ALC285_FIXUP_LENOVO_HEADPHONE_NOISE, and
this FIXUP is specific several lenovo laptop models. I have tested audio and
led functions on those machines.
