radix tree: remove unused variable
Recent versions of clang warn about an unused variable, though older versions saw the 'slot++' as a use and did not warn: radix-tree.c:1136:50: error: parameter 'slot' set but not used [-Werror,-Wunused-but-set-parameter] It's clearly not needed any more, so just remove it.
