Masahiko Sawada 80d5d4937c Fix potential integer handling issue in radixtree.h. 
Coverity complained about the integer handling issue; if we start with
an arbitrary non-negative shift value, the loop may decrement it down
to something less than zero before exiting. This commit adds an
assertion to make sure the 'shift' is always 0 after the loop, and
uses 0 as the shift to get the key chunk in the following operation.

Introduced by ee1b30f12.
