ALSA: hda - Fix broken reconfig
The HD-audio reconfig function got broken in the recent kernels, typically resulting in a failure like: snd_hda_intel 0000:00:1b.0: control 3:0:0:Playback Channel Map:0 is already present This is because of the code restructuring to move the PCM and control instantiation into the codec drive probe, by the commit [bcd96557bd0a: ALSA: hda - Build PCMs and controls at codec driver probe]. Although the commit above removed the calls of snd_hda_codec_build_pcms() and *_build_controls() at the controller driver probe, the similar calls in the reconfig were still left forgotten. This caused the conflicting and duplicated PCMs and controls. The fix is trivial: just remove these superfluous calls from reconfig_codec().
