Applied to 4.6/scsi-queue.

[PATCH] ibmvfc: byteswap scsi_id, wwpn, and node_name prior to logging

[Tyrel Datwyler]

When logging async events the scsi_id, wwpn, and node_name values
are used directly from the CRQ struct which are of type __be64. This
can be confusing to someone looking through the log on a LE system.
Instead byteswap these values to host endian prior to logging.
