correctly select first log item to push

Under heavy metadata load we are seeing log hangs. The
AIL has items in it ready to be pushed, and they are within
the push target window. However, we are not pushing them
when the last pushed LSN is less than the LSN of the
first log item on the AIL. This is a regression introduced
by the AIL push cursor modifications.
