lockup_detector: init lockup detector after all the init_calls

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8LQCC


CVE: NA

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

We call 'sdei_init' as 'subsys_initcall_sync'. lockup detector need to
be initialised after sdei_init. The influence of this patch is that we
can not detect the hard lockup in init_calls.
