[PATCH] sched/fair: Remove redundant error handling path in alloc_fair_sched_group

[Wanwu Li <liwanwu9113@163.com>]

From: Wanwu Li <liwanwu@kylinos.cn>

On error, the sched_free_group function already centrally handles
resource cleanup, making the explicit kfree(cfs_rq) in
alloc_fair_sched_group redundant.
