[S390] clock sync mode flags
The clock sync mode flag CLOCK_SYNC_STP is not cleared when stp is set offline. In this case the get_sync_clock() function returns -EACCESS and the dasd driver will block all i/o until stp is enabled again. In addition get_sync_clock can return -EACCESS if the clock is not in sync instead of -EAGAIN. Rework the stp/etr online handling to fix these problems.
