ipmi: fix oob access due to uninit smi_msg type
We're hitting OOB accesses in handle_ipmb_direct_rcv_rsp() (memcpy of
size -1) after user space generates a message. Looks like the message
is incorrectly assumed to be of the new IPMB type, because type is never
set and message is allocated with kmalloc() not kzalloc().
Fixes: 059747c245f0 ("ipmi: Add support for IPMB direct messages")
