[PATCH 2/3] s390/vdso: fix arch_data access for __arch_get_hw_counter()

Li Wang reported that clock_gettime(CLOCK_MONOTONIC_RAW, ...) returns incorrect values when time is provided via vdso instead of system call: vdso_ts_nsec = 4484351380985507, vdso_ts.tv_sec = 4484351, vdso_ts.tv_nsec = 380985507 sys_ts_nsec = 1446923235377, sys_ts.tv_sec = 1446, sys_ts.tv_nsec
