[ Upstream commit 5a0c72c1da3cbc0cd4940a95d1be2830104c6edf ]

The workaround for Dell machines to skip the pin-shutup for mic pins
introduced alc_headset_mic_no_shutup() that is replaced from the
generic snd_hda_shutup_pins() for certain codecs. The problem is that
the call is done unconditionally even if spec->no_shutup_pins is set.
This seems causing problems on other platforms like Lenovo.

This patch corrects the behavior and the driver honors always
spec->no_shutup_pins flag and skips alc_headset_mic_no_shutup() if
it's set.
