[Crash-utility] issue: runq -g

[vinayak menon]

Hi Dave,

I was getting the following error upon executing "runq -g".

runq: invalid structure member offset: cfs_rq_throttled
      FILE: task.c  LINE: 7615  FUNCTION: print_group_header_fair()

[./crash] error trace: 80e98b0 => 80e9815 => 80e577f => 8143bde

"cfs_bandwidth" is available in task_group irrespective of whether
CONFIG_CFS_BANDWIDTH is enabled or not (but empty). But "throttled" is
available in cfs_rq only if config is enabled. The following patch
fixes this.
