    file-jpeg: Make cinfo struct static so asynchronous saves don't crash
    
    The plug-in already makes a copy of the cinfo struct for asynchronous
    save, but it seems that somewhere inside cinfo, a pointer points to
    another region in this struct. So, everything is copied as-is, and
    the pointer ends up pointing to somewhere in the save_image() stack
    which is gone when that function returns.
