    GFile: remove some unnecessary code
    
    The "mainloop_barrier" in copy_async_thread() is unnecessary, since
    the g_simple_async_result_complete_in_idle() will be queued after all
    of the g_io_scheduler_job_send_to_mainloop_async()s, and sources with
    the same priority will run in the order in which they were queued.
