locking/rt: Add sparse annotation for RCU.
Every lock, that becomes a sleeping lock on PREEMPT_RT, starts a RCU read
side critical section. There is no sparse annotation for this and sparse
complains about unbalanced locking.
Add __acquires/ __releases for the RCU lock. This covers all but the
trylock functions. A __cond_acquires() annotation didn't work.
