Lioncash b4f63db04e nfp: Correct erroneous sizeof expression within GetTagInfo()
The previous expression would copy sizeof(size_t) amount of bytes (8 on
a 64-bit platform) rather than the full 10 bytes comprising the uuid
member.

Given the source and destination types are the same, we can just use an
assignment here instead.
