drivers/ipmi: Fix multiple issues

* Set abort command define
* Set debug level to SPEW
* Support zero length data packet in ipmi_kcs_send_message
  That's required for commands like GET_DEVICE_ID, which have no
  additional data to send.
* Read reply even if given no receive buffer
* Prevent buffer overflow in read reply processing

Tested on Wedge100s.
