rcu: Make rcu_implicit_dynticks_qs() locals be correct size
When the ->dynticks field in the rcu_dynticks structure changed to an atomic_t, its size on 64-bit systems changed from 64 bits to 32 bits. The local variables in rcu_implicit_dynticks_qs() need to change as well, hence this commit. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
