Fix regression for tracing asn1c enc/dec tracing

As described in common/utils/config.h, it is possible to hook into the
asn1c tracing mechanism to print logs.

This commit fixes a regression to print theses traces properly in OAI.
Above-mentioned file explains also how to reduce the amount of logs,
e.g., for single code blocks.
