Subject: [PATCH 2/3] Revert "Documentation: LKMM: Move MP+onceassign+derefonce to new litmus-tests/rcu/"

This reverts commit a5cca3485d9206a9dbbc6f47d2a537e69b53cd82.

MP+onceassign+derefonce.litmus is called out from
tools/memory-model/Documentation/recipes.txt.
It should be in the same directory as the other representative tests
to help readers inspect it.
