docs: rbtree.txt: fix Sphinx build warnings

Browse Source 
Ths file is already at ReST format. Yet, some recent changes
made it to produce a few warnings when building it with
Sphinx.

Those are trivially fixed by marking some literal blocks.

Fix them before adding it to the docs building system.

overhead for maintanence; albeit larger memory footprint.
Similar to the rb_root structure, cached rbtrees are initialized to be
empty via:
empty via::
struct rb_root_cached mytree = RB_ROOT_CACHED;
Cached rbtree is simply a regular rb_root with an extra pointer to cache the
leftmost node. This allows rb_root_cached to exist wherever rb_root does,
which permits augmented trees to be supported as well as only a few extra
interfaces:
interfaces::
struct rb_node *rb_first_cached(struct rb_root_cached *tree);
void rb_insert_color_cached(struct rb_node *, struct rb_root_cached *, bool);
void rb_erase_cached(struct rb_node *node, struct rb_root_cached *);
Both insert and erase calls have their respective counterpart of augmented
trees:
trees::
void rb_insert_augmented_cached(struct rb_node *node, struct rb_root_cached *,
bool, struct rb_augment_callbacks *);
