rcutorture: Convert call_rcu() to call_rcu_flush()

The rcutorture kernel module was designed with the notion that call_rcu()
pretty much immediately starts a grace period, which is no longer the case
for kernels built with CONFIG_RCU_LAZY=y.  This commit therefore converts
rcutorture's call_rcu() invocations to call_rcu_lazy().
