pml/ob1: fixed local handle sent during PUT control message

In case of using a btl_put in ob1, the handle of the locally registered
memory is sent with a PUT control message. In the current master code
the sent handle is necessary the handle in the frag but if the handle
has been successfully registered in the request, the frag structure does
not have any valid handle and all fragments use the request one.

I suggest to check if the handle in the fragment is valid and if not to
send the handle from the request.
