[S390] etr/stp: put correct per cpu variable

Browse Source 
Fix this compile error in linux-next:

arch/s390/kernel/time.c: In function 'get_sync_clock':
arch/s390/kernel/time.c:337: error: 'clock_sync_sync' undeclared (first use in this function)

Gets exposed because the new per cpu code references the variable
passed to put_cpu_var. This was not a real bug.
