[PATCH 2/2] ASoC: Remove unused "n_widgets" field from snd_soc_dapm struct

[Lars-Peter Clausen <lars@metafoo.de>]

Commit 497098be ("ASoC: dapm: Remove bodges for no-widget CODECs") removed the
last user of the n_widgets field. Currently it is incremented for each widget
added, but the value is never used, so we can remove it.
