Mikko Perttunen b06375f360 gpu: host1x: Set waiter output reference within lock ...

With the new fence implementation, we need to assign the reference
within the lock. Otherwise, it can happen that the waiter may get
signaled before the pointer has been set, and the fence implementation
will try to call intr_put_ref with a NULL pointer.
