lib/radix-tree.c: fix uninitialized variable compilation warning
We need to set an initial value for offset to eliminate compilation
warning.
How to reproduce warning:
$ make -C tools/testing/radix-tree
radix-tree.c: In function `radix_tree_tag_clear':
radix-tree.c:1046:17: warning: `offset' may be used uninitialized in this function [-Wmaybe-uninitialized]
1046 | node_tag_clear(root, parent, tag, offset);
