rcu: Use pr_alert/pr_cont for printing logs
User pr_alert/pr_cont for printing the logs from rcutorture module directly instead of writing it to a buffer and then printing it. This allows us from not having to allocate such buffers. Also remove a resulting empty function. I tested this using the parse-torture.sh script as follows: $ dmesg | grep torture > log.txt $ bash parse-torture.sh log.txt test $ There were no warnings which means that parsing went fine.
