RFR: 8313231: Redundant if statement in ZoneInfoFile

[John Jiang]

if (i < savingsInstantTransitions.length) {
    // javazic writes the last GMT offset into index 0!
    if (i < savingsInstantTransitions.length) {
        offsets[0] = standardOffsets[standardOffsets.length - 1] * 1000;
        nOffsets = 1;
    }
    ...
}


The second if statement looks unnecessary.
