[PATCH] event-loop: always do the post-dispatch check

[Ander Conselvan de Oliveira]

The post-dispatch check on wl_event_loop_dispatch() was not being run
if epoll_wait returned 0 events, making the check unreliable.

With the changes on Weston to process input during output repaint, this
bug was actually preventing input to be processed on the X11 compositor
while repaint was being called from weston_output_finish_frame().
