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

Browse Source 
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.
