torture: Make torture.sh refscale runs use verbose_batched module parameter
On large systems, the refscale printk() rate can overrun the file system's ability to accept console log messages. This commit therefore uses the new verbose_batched module parameter to rate-limit some of the higher-rate printk() calls. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
