common: move workqueue handling from poller_call() to sched()

Workqueues are run out of poller_call, not because of a dependency, but
because when they were added, poller_call was directly called from
is_timeout.

With the addition of bthreads, there is now a general resched() function
that runs pollers and switches between bthreads. It makes sense to move
workqueue handling there as well to keep scheduling matter contained in
a single function. Do so.
