Carlo Marcelo Arenas Belón 14825944d7 oidtree: avoid nested struct oidtree_node ...

92d8ed8ac1 (oidtree: a crit-bit tree for odb_loose_cache, 2021-07-07)
adds a struct oidtree_node that contains only an n field with a
struct cb_node.

unfortunately, while building in pedantic mode witch clang 12 (as well
as a similar error from gcc 11) it will show:

  oidtree.c:11:17: error: 'n' may not be nested in a struct due to flexible array member [-Werror,-Wflexible-array-extensions]
          struct cb_node n;
                         ^

because of a constrain coded in ISO C 11 6.7.2.1¶3 that forbids using
structs that contain a flexible array as part of another struct.

use a strict cb_node directly instead.
