ipmi: Don't flush messages in sender() in run-to-completion mode

When flushing queued messages in run-to-completion mode,
smi_event_handler() is recursively called.

flush_messages()
 smi_event_handler()
  handle_transaction_done()
   deliver_recv_msg()
    ipmi_smi_msg_received()
     smi_recv_tasklet()
      sender()
       flush_messages()
        smi_event_handler()
         ...

The depth of the recursive call depends on the number of queued
messages, so it can cause a stack overflow if many messages have
been queued.

To solve this problem, this patch removes flush_messages()
from sender()@ipmi_si_intf.c.  Instead, add flush_messages() to
caller side of sender() if needed.  Additionally, to implement this,
add new handler flush_messages to struct ipmi_smi_handlers.
