rcu: Rename rcu_implicit_dynticks_qs() into rcu_watching_snap_recheck()
The context_tracking.state RCU_DYNTICKS subvariable has been renamed to RCU_WATCHING, drop the dyntick reference and update the name of this helper to express that it rechecks rdp->watching_snap after an earlier rcu_watching_snap_save().
