In gbaudio_dapm_free_controls(), if one of the widgets is not found, an error

This patch fixes the bug. If if one of them is not found, just skip and free the others.
Apart from the typo, please break your lines at 72 columns or so (not
needed for the Fixes tag).
Thanks for review, Do I need to send a v2 patch to change the
commit msg?

Not sure if we can ever have the widget lookup fail, but at least this
looks consistent now.
