[PATCH 2/2] Documentation: RCU: Retitle toctree index

[Bagas Sanjaya]

toctree index title ("RCU concepts") is rather a misnomer: RCU concepts
is already described in rcu.rst, whereas the toctree suggests that
the docs themes about handbook on RCU subsystem instead.

Edit the title to reflect the fact.
