Subject: lib/vsprintf: simplify UUID printing
There are few functions here and there along with type definitions that
provide UUID API. This series consolidates everything under one hood and
converts two current users.
This patch (of 8):
Since we have hex_byte_pack_upper() we may use it directly and avoid second
loop.
