ALSA: hda - Refresh sysfs at snd_hda_codec_update_widgets()

In the commit [fa4f18b4: ALSA: hda - Refresh widgets sysfs at
probing Haswell+ HDMI codecs], snd_hdac_refresh_widget_sysfs() is
explicitly called in the codec driver.  But this results in refreshing
twice, as snd_hdac_refresh_widget_sysfs() itself calls
snd_hdac_refresh_widgets() function.

Instead, we can replace the call in snd_hda_codec_update_widgets()
with snd_hdac_refresh_widget_sysfs().  This also fixes the missing
sysfs update for ca0132, too.
