taskstats: drop the dead NULL attribute check in parse()

Patch series "taskstats: tidy up the cpumask command path". Two small cleanups from reading kernel/taskstats.c. No functional change in either one. This patch (of 2): taskstats_user_cmd() only calls the cpumask handlers after checking the same info->attrs[] entry, so parse() never sees a NULL attribute. Drop the check and its odd "return 1", which no caller tested for anyway. No functional change.
