category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4WKMY


CVE: NA

--------------------------------

cfs_bandwidth_usage_inc() need hold jump_label_mutex and
might sleep, so we can not call it in atomic context.
Fix this by moving cfs_bandwidth_usage_{inc,dec}() out of
rcu read critical section.
