num2str(): Fix overflow handling

This patch changes the output for the arguments (UINT64_MAX, 4, 1, 0,
N2S_NONE, "18.4") from "18.4(null)" into "18.4".

This patch fixes the following Coverity complaint:

CID 169307 (#1 of 1): Out-of-bounds read (OVERRUN)
27. overrun-local: Overrunning array of 6 8-byte elements at element
    index 6 (byte offset 55) by dereferencing pointer unitprefix + post_index.
