ALSA: hda - Fix resume from StR of HP 2510p with docking-station 

When HP laptop with AD1981 codec is suspended and the docking-station
is connected before the resume, the outputs get confused, and wrongly
routed still to the speaker.  This is because of a change in 2.6.34-rc1

    ALSA: hda: Add powerdown for Analog Devices HDA codecs

The problem was the added resume callback that doesn't consider the
modified init hook.  The fix is simply remove the resume callback here
and make the resume normally.  This doesn't change any behavior intended
in the commit above (for shutting down the sound at suspend) but only
fixes the resume.
