With offline cpus no longer beeing seen in nohz mode (ts->idle_active=0), we
don't need the check for cpu_online() introduced in commit 7386cdbf. Offline

Please also specify the summary of that commit in parens (or however you like).

cpu's idle time as last recorded in its ts->idle_sleeptime will be reported
(thus excluding its offline time as part of idle time statistics).
