Paul E. McKenney d465492a22 srcu: Guarantee non-negative return value from srcu_read_lock() ...

For almost 20 years, the int return value from srcu_read_lock() has
been always either zero or one.  This commit therefore documents the
fact that it will be non-negative, and does the same for the underlying
__srcu_read_lock().
