[Trivial] Fix errant LogPrint in UpdateZPIVSupply

The `LogPrint()` at the end of this function was missing a `,` separator
between the category and the message, as well as returning the two
paramaters in reverse order when compared to similar log prints.

The missing `,` was causing a segfault when running with `-debug` or
`-debug=zero`
