* @pring: Pointer to the driver internal I/O ring.
* @piocbq: Pointer to the IOCBQ.
* @dmabuf: pointer to a dmabuf that describes the FC sequence
*
* This function serves as the default handler for the sli4 unsolicited
* abort event. It shall be invoked when there is no application interface
* registered unsolicited abort handler. This handler does nothing but
* just simply releases the dma buffer used by the unsol abort event.
* This function serves as the upper level protocol abort handler for CT
* protocol.
*
* Return 1 if abort has been handled, 0 otherwise.
