unix: fix small write immediately followed by uv_read_stop never comp…

…letes uv__io_feed() would not update the pending events masked to include UV__POLLOUT, so a subsequent uv__io_stop() call to remove the UV__POLLIN event would cause the pevents mask to become zero. When the pevents mask would be zeroed, the io watcher would be removed from the pending queue.
