Subject: lib/generic-radix-tree.c: make 2 functions static inline
When building with W=1, we get some warnings:
l CC lib/generic-radix-tree.o
lib/generic-radix-tree.c:39:10: warning: no previous prototype for 'genradix_root_to_depth' [-Wmissing-prototypes]
39 | unsigned genradix_root_to_depth(struct genradix_root *r)
| ^~~~~~~~~~~~~~~~~~~~~~
lib/generic-radix-tree.c:44:23: warning: no previous prototype for 'genradix_root_to_node' [-Wmissing-prototypes]
44 | struct genradix_node *genradix_root_to_node(struct genradix_root *r)
| ^~~~~~~~~~~~~~~~~~~~~
They're not used anywhere else, so make them static inline.
