[PATCH 1/2] taskstats: drop the dead NULL attribute check in parse()

[Bradley Morgan <include@grrlz.net>]

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.
