When the IPMI message handler requested that the interface look for events,
the ipmi_si driver would request flags, see if the event buffer full flag was
set, then request events.  It's better to just send the request for events, as
it cuts one message out of the transaction if there happens to be events, and
it will fetch events even if the event buffer was not full.
