ui/gtk: graphic_hw_gl_flushed after closing dmabuf->fence_fd 

The dmabuf often becomes invalid right after unblocking pipeline
and graphic_hw_gl_flushed in case a new scanout blob is submitted
because the dmabuf associated with the current guest scanout is
freed after swapping.

So both graphic_hw_gl_block and graphic_hw_gl_flushed should be
executed after closing fence_fd for the current dmabuf.
