RFR: Fix tiny diff vs upstream

[Roman Kennke]

And there is another one:

diff -r 7d6955d6d501 src/hotspot/share/opto/node.cpp
--- a/src/hotspot/share/opto/node.cpp   Tue Jan 08 14:53:11 2019 +0100
+++ b/src/hotspot/share/opto/node.cpp   Mon Jan 14 11:59:09 2019 +0100

While upstream is probably wrong there, it doesn't seem our issue to
carry a fix. Let's just revert to upstream.

Ok?
