mdc_finish used to set this field once it had successfully verified
the MDC packet, with its only reader in the same function. This was
removed by a59ee88197 when mdc_finish stopped being called through
the pullf_read API, the field has been unused since.
Note that MDC verification does not rely on it: process_data_packets
tracks whether an MDC packet was seen in its local got_mdc variable
and rejects the message if a required MDC is missing, while the
use_mdcbuf_filter path checks the hash in mdcbuf_finish().
