anv/wsi: Avoid stuck Wayland connection

Browse source 
In acquire_next_image, we are waiting for a wl_buffer::release to arrive
and release one of the buffers in our swapchain. Most compositors don't
explicitly flush release events, so we may need to perform a roundtrip
instead, to ensure the event arrives.
