kernel/poll: Remove dummy waitq from stack

Browse source 
The poll code uses a dummy wait queue so the threads have something to
block on, but the previous coherence pass (which rearranged things to
put the _poller data elsewhere) missed that this was on the stack,
which is not allowed.  It actually has no use except as a list, so
make it a global static instead.
