    So that it can show a proper debug message in the right place.  The
    check_variable() is used in other places which don't want to print the
    message.
    
      $ perf --debug type-profile annotate --data-type
    
    Before:
      -----------------------------------------------------------
      find data type for 0x140(reg14) at update_blocked_averages+0x2db
      CU for kernel/sched/fair.c (die:0x12dd892)
      frame base: cfa=1 fbreg=7
      no pointer or no type                                         <<<--- removed
      check variable "__mptr" failed (die: 0x13022f1)
       variable location: base=reg14, offset=0x140
       type='void*' size=0x8 (die:0x12dd8f9)
    
    After:
      -----------------------------------------------------------
      find data type for 0x140(reg14) at update_blocked_averages+0x2db
      CU for kernel/sched/fair.c (die:0x12dd892)
      frame base: cfa=1 fbreg=7
