Various security techniques can obfuscate pointer printouts on the console. Unfortunately, rcutorture relies on either "null" or all zeroes to identify the last few statistics printouts at the end of the test. These need to be identified because failing to do so will results in false-positive complaints about grace-period hangs. This commit therefore prints the "ver:" in capitals ("VER:") when the RCU-protected pointer has been set to NULL, which causes rcutorture's parse-console.sh script to correctly ignore these lines.
