staging: greybus: codecs: fix type confusion of list iterator variable

Browse Source 
[ Upstream commit 84ef256550196bc06e6849a34224c998b45bd557 ]

If the list does not exit early then data == NULL and 'module' does not
point to a valid list element.
Using 'module' in such a case is not valid and was therefore removed.
