sched/smt: fix unbalance sched_smt_present dec/inc

category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7YBSW


CVE: NA

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

If cpuset_cpu_inactive() fails in sched_cpu_deactivate(), the
cpu offline failed, but sched_smt_present is decreased before
calling sched_cpu_deactivate, it leads unbalance dec/inc, so
fix it by increasing sched_smt_present in the error path.
