rcutorture: remove synchronize_rcu from readers
This gives much worse numbers for readers, especially if synchronize_rcu
is made more expensive as is the case with --enable-membarrier. Before:
$ tests/rcutorture 10 stress 10
n_reads: 98304 n_updates: 529 n_mberror: 0
rcu_stress_count: 98302 2 0 0 0 0 0 0 0 0 0
After:
$ tests/rcutorture 10 stress 10
n_reads: 165158482 n_updates: 429 n_mberror: 0
rcu_stress_count: 165154364 4118 0 0 0 0 0 0 0 0 0
