rcu: Reduce dyntick-idle state space
Both extended-quiescent-state entry and exit first update the nesting counter and then adjust the dyntick-idle state. This means that there are four states: (1) Both nesting and dyntick idle indicate idle, (2) Nesting indicates idle but dyntick idle does not, (3) Nesting indicates non-idle and dyntick idle does not, and (4) Both nesting and dyntick idle indicate non-idle. This commit simplifies the state space by eliminating #3, reversing the order of updates on exit from extended quiescent state. Signed-off-by: Paul E.
