s390x/cpu: Use timer_free() in the finalize function to avoid memleaks
When running device-introspect-test, a memory leak occurred in the s390_cpu_initfn
function, this patch use timer_free() in the finalize function to fix it.
ASAN shows memory leak stack:
Direct leak of 3552 byte(s) in 74 object(s) allocated from:
