hw/s390x: Fix bad mask in time2tod()
Since "s390x/tcg: avoid overflows in time2tod/tod2time", the time2tod() function tries to deal with the 9 uppermost bits in the time value, but uses the wrong mask for this: 0xff80000000000000 should be used instead of 0xff10000000000000 here. Fixes:stable-3.014055ce53c
