Ben Kallus ddbff4e235 IMPORT: ebtree: Fix UB from clz(0) ...

From 'man gcc': passing 0 as the argument to "__builtin_ctz" or
"__builtin_clz" invokes undefined behavior. This triggers UBsan
in HAProxy.

[wt: tested in treebench and verified not to cause any performance
 regression with opstime-u32 nor stress-u32]
