resctrl: fix undefined reference to lockdep_is_cpus_held() 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8T2RT



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

lockdep_is_cpus_held() will only be compiled by the kernel when
CONFIG_HOTPLUG_CPU is defined. Otherwise, kernel test robot would report
the following compile error:

ld: vmlinux.o: in function `resctrl_get_domain_from_cpu':
include/linux/resctrl.h:291: undefined reference to `lockdep_is_cpus_held'

Reported-by: default avatarkernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202401252038.VOiTn1TA-lkp@intel.com/
