afs: Remove SRXAFSCB_GetDE
The GetDE RPC has been commented out from afscbint.xg effectively
since it was introduced, but we still define the SRXAFSCB_GetDE server
stub for it.
This is useless, but also potentially dangerous, since the stub
routine just returns success, without populating the output arguments.
One of the output arguments is a string, and so if this RPC is
actually run, the rxgen-generated server code will try to xdr_string()
that string. Since we never set it to anything, this will result in
xdr_string trying to dereference a NULL pointer.
None of this actually happens currently, since the GetDE RPC is
commented out. But to avoid the above situation if it's ever
uncommented, remove the useless SRXAFSCB_GetDE function.
