iio: Add a helper to free a list of IIO device attributes
We have the same code to free a IIO device attribute list in multiple place. This patch adds a new helper function to take care of this and replaces the custom instances with a call to the helper function. Note that we do not need to call list_del() for each of the list items since we will never look at any of the list items nor the list itself again.
