Drag the common parts out of the if-else. This also means that
qsizetype size() is no longer truncated in the assignment to quint32
len, but that doesn't fix the problem that we create invalid Qt 5
streams when the QBitArray has more than INT_MAX bits in it. That is
for a follow-up patch (which is why the {} stay for now).
As a drive-by, replace verbose constData() with data() (the QByteArray
is already const).
Pick-to: 6.7 6.6 6.5 6.2
