Subject: [PATCH v3 20/25] rcu: Rename struct rcu_data .exp_dynticks_snap into .exp_watching_snap
The context_tracking.state RCU_DYNTICKS subvariable has been renamed to
RCU_WATCHING, and the snapshot helpers are now prefix by
"rcu_watching". Reflect that change into the storage variables for these
snapshots.
