posix-cpu-timer: Unify the now redundant code in lookup_task
Now that both !thread paths through lookup_task call thread_group_leader, unify them into the single test at the end of lookup_task. This unification just makes it clear what is happening in the gettime special case of lookup_task. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
