srcu: Avoid NULL dereference in srcu_torture_stats_print()
You really shouldn't invoke srcu_torture_stats_print() after invoking
cleanup_srcu_struct(), but there is really no reason to get a
compiler-obfuscated per-CPU-variable NULL pointer dereference as the
diagnostic. This commit therefore checks for NULL ->sda and makes a
more polite console-message complaint in that case.
