    windows-x11.c: Fix leaked error trap
    
    The merge of the commit af46ef3b 'meta_window_new: clean up error handling'
    to the wayland branch accidentally added an extra call to meta_error_trap_push(),
    meaning that we leaked one level of error traps for each new window.
    
    Fixes warning:
      Gdk-WARNING **: XSetErrorHandler() called with a GDK error trap pushed.
