present: actually return the created notifies

Browse source 
present_create_notifies() creates an array of notifies but never returns
them to the caller, despite them being passed individually to
present_add_window_notify(). The caller proceeds with a NULL notifies
array, eventually causing an OOB in present_vblank_notify() when
vblank->notifies is NULL.
