I don't think these helpers are overly useful.

tout is always one in the only caller and thus doesn't need to be
passed.  But I think you really want a timeout of 0 here to queue it up
ASAP (it translates to a direct queue_work() call internally).

Also this function could simply be merged into it's only and relatively
simple caller.
