ZendPack::unpack() always returns a signed int32_t,
regardless of actual storage type being unpacked. For 32bit
unsigned types ('L', 'N', 'V', and 'I'(on I32 systems)) this
means overflowing in the helper and we have to explicitly
recast it to a uint64_t to get the data back out.
For LNV, this was already handled, it was missed for I.
