[eio] Bug breaking on maxreqs

Hi Marc,

If you send many requests to eio and set either max_poll_reqs or
max_poll_time, then it is possible to get into a situation where
pending responses are sitting on the queue but want_poll hasn't been
called. A solution which, works for me, is to call want_poll_cb() at
the bottom of etp_poll() when someone has broken out of the loop.
