Subject: [PATCH 21/38] tick-sched: no need to rewrite '1' to tick_nohz_enabled

NO_HZ feature can be enabled/disabled from bootargs if we have a string 'nohz='
followed by 'on' or 'off'. The default value of this variable is '1'.  When 'on'
is passed as bootarg, we don't have to overwrite this variable by '1'.

Also, an extra blank line is removed.
