kernel/poll: Store the work queue in the triggered work poll items

Browse source 
The poll code was playing this weird trick where the thread pointer in
the "struct _poller" object for a triggered work item.  It would not
be a thread to wake up, but instead a pointer to the (non-polling)
thread operated by the work queue being triggered.  The code would
never touch this thread, just use it as a way to get a pointer to the
enclosing work queue struct.

Just store the work queue pointer in the first place.  It's much
simpler, and makes future modifications to remove that thread pointer
possible.
