dix: don't prepend an activated passive grab to the listeners 

If the device is currently grabbed as the result of a passive grab
activating, do not prepend that grab to the listeners (unlike active grabs).
Otherwise, a client with a passive pointer grab will prevent touch grabs
from activating higher up in the window stack.
