ALSA: hda - Fix redundant jack creations for cx5051

[Note that since the patch isn't applicable (and unnecessary) to
3.3-rc, there is no corresponding upstream fix.]

The cx5051 parser calls snd_hda_input_jack_add() in the init callback
to create and initialize the jack detection instances.  Since the init
callback is called at each time when the device gets woken up after
suspend or power-saving mode, the duplicated instances are accumulated
at each call.  This ends up with the kernel warnings with the too
large array size.

The fix is simply to move the calls of snd_hda_input_jack_add() into
the parser section instead of the init callback.

The fix is needed only up to 3.2 kernel, since the HD-audio jack layer
was redesigned in the 3.3 kernel.
