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

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. Signed-off-by: Tyrel Datwyler
