Fix the return value of pack_pldm_header and unpack_pldm_header

- The intent behind this commit is to fix the return value of the
  pack_pldm_header and the unpack_pldm_header methods.

- According to PLDM spec, their return value should be `uint8_t`, not
  `int`, so 0 is PLDM_SUCCESS and non-0 is failure.

- Also, when we call the pack_pldm_header and unpack_pldm_header
  methods, we need to verify the return value of the method.

Tested: Built pldm successfully and Unit Test passes.
