rcu: Upgrade sync_exp_work_done() to smp_mb()
The sync_exp_work_done() function uses smp_mb__before_atomic(), but
there is no obvious atomic in the ensuing code. The ordering is
absolutely required for grace periods to work correctly, so this
commit upgrades the smp_mb__before_atomic() to smp_mb().
Fixes: 6fba2b3767ea ("rcu: Remove deprecated RCU debugfs tracing code")
