srcu: Fix rcutorture-statistics typo

The function srcutorture_get_gp_data() duplicated the check for sp->batch_check0.head instead of also checking sp->batch_check1.head. The only effect of this typo would be for rcutorture statistics to understate the fraction of time that an SRCU grace period was in flight, and only for Classic SRCU. This commit fixes this typo.
