dsp: base: Rework {un,}pack_pldm_header() error handling

The current preference is that library APIs return negative errno values
to signal implementation errors. That doesn't jive with existing stable
APIs returning PLDM completion codes, so provide a means to translate
between the two.

The first users are the {un,}pack_pldm_header() functions.
