[PATCH] sched/core: fix formatting issues in sched_can_stop_tick()

sched_can_stop_tick() was using 7 spaces instead of 8 spaces or a 'tab' at the
beginning of each line. Which doesn't align with the Coding Guidelines.

Also it removes the *rq variable as it was used at only one place and hence we
can directly use this_rq() instead.

I don't think rq = tihs_rq() has to be done before smp_mb(), in case yes sorry
for this patch :(
