2013-05-02[SCSI] ibmvfc: Suppress ABTS if target goneBrian King
Adds support for a new VIOS feature that allows ibmvfc to optimize terminate_rport_io by telling the VIOS the target is no longer accessible on the fabric and that it should not send an ABTS out on the fabric to the device.

2013-05-02[SCSI] ibmvfc: Send cancel when link is downBrian King
If attempting to abort requests due to a fail fail timeout or error handling while the link is down, we cannot send an abort out on the fabric. We can, however, send a cancel to the VIOS. This fixes ibmvfc to send a cancel in this case to prevent error handling from failing and/or escalating.
