fix byte order in EDE logging

fix byte order in EDE logging

When an EDE code is added to a message, the code is converted early in a
big-endian order so it can be memcpy-ed directly in the EDE buffer that
will go on the wire.

This previous change forget to update debug logs which still assume the
EDE code was in host byte order. Add a separate variable to
differentiate both and avoid ambiguities
