api: fix printf format specifier

- Use %hu for unsigned short instead of %u.

Prior to this change some compilers could warn of an argument type
mismatch. C argument promotion rules promote the unsigned short argument
to an int, which does not match %u (unsigned int) but does match %hu
(unsigned short).

Assisted-by: Viktor Szakats
