treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()
Browse files Browse the repository at this point in the history
This converts all the existing DECLARE_TASKLET() (and ...DISABLED)
macros with DECLARE_TASKLET_OLD() in preparation for refactoring the
tasklet callback type. All existing DECLARE_TASKLET() users had a "0"
data argument, it has been removed here as well.
