    s3:smb2_notify: fix use after free on long living notify requests
    
    This is a hack, but it should fix the bug:
    
       change_notify_add_request() talloc moves smb_request away,
       which is not expected by the smb2_notify.c code...
    
       smbd_smb2_notify_reply() uses tevent_req_defer_callback()
       (in older versions an immediate event) to defer the response.
       This is needed as change_notify_reply() will do more things
       after calling reply_fn() (smbd_smb2_notify_reply is this case)
       and often change_notify_remove_request() is called after
       change_notify_reply().
    
       change_notify_remove_request() implicitly free's the smb_request
       that was passed to change_notify_add_request().
    
       smbd_smb2_fake_smb_request() added the smb_request as smb2req->smb1req,
       which is expected to be available after smbd_smb2_notify_recv() returned.
    
    The long term solution would be the following interface:
    
    struct tevent_req *change_notify_request_send(TALLOC_CTX *mem_ctx,
                                                  struct tevent_context *ev,
                                                  struct files_struct *fsp,
                                                  uint32_t max_length,
                                                  uint32_t filter,
                                                  bool recursive);
    NTSTATUS change_notify_request_recv(struct tevent_req *req,
                                        TALLOC_CTX *mem_ctx,
                                        DATA_BLOB *buffer);
