srcu: Reduce scans of srcu_data in counter wrap check Currently, given a multi-level srcu_node tree, SRCU can scan the full set of srcu_data structures at each level when cleaning up after a grace period. This, though harmless otherwise, represents pointless overhead. This commit therefore eliminates this overhead by scanning the srcu_data structures only when traversing the leaf srcu_node structures.
