dco: add standard mi prefix handling to multi_process_incoming_dco()

Our code generally expects functions that deal with a multi instance
to set up a log prefix at the beginning with set_prefix(mi) and clear
it at the end with clear_prefix().

Add the calls to multi_process_incoming_dco() in a similar way to
what is done for multi_process_incoming_link() - handling "link
events" and "dco events" the same, with correct prefix in the
function and no leftover prefix afterwards.
