[PATCH] sched: fix up fs/proc/array.c whitespace problems

while changing task_stime() i noticed a whitespace style problem in
array.c - fix it. While at it, fix all the other style problems too,
most of them in the scheduler-stats related portions of array.c.

There is no change in functionality:

   text    data     bss     dec     hex filename
   4356      28       0    4384    1120 array.o-before
   4356      28       0    4384    1120 array.o-after
