BUG/MINOR: lru: fix the standalone test case for invalid revision

In 2.6, a build issue for LRU in standalone test mode was addressed by
commit bf9c07fd9 ("BUILD/DEBUG: lru: update the standalone code to
support the revision"), but using revision 1 while looking up rev 0
results in 100% misses. Let's fix this and commit with revision 0 as
well.

No backport is needed, this only happens when hacking on the code.
