QArrayData: catch negative capacities earlier

This isn't necessary because we would catch it inside of
calculateBlockSize() → qCalculateBlockSize(), because the negative
elementCount becomes a large positive one after the conversion to
size_t.

But since this change is effectively free anyway, we can do it and avoid
a future in which those functions don't convert to an unsigned type.
