    sched: clean up schedstats, cnt -> count
    
    rename all 'cnt' fields and variables to the less yucky 'count' name.
    
    yuckage noticed by Andrew Morton.
    
    no change in code, other than the /proc/sched_debug bkl_count string got
    a bit larger:
    
       text    data     bss     dec     hex filename
      38236    3506      24   41766    a326 sched.o.before
      38240    3506      24   41770    a32a sched.o.after
