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.
