v2: Fix endianness of WWNN/WWPN. [Paolo] This series implements the proposed fc_host feature of virtio-scsi. The first patch updates the data structure changes according to the spec proposal; the second patch actually implements the operations.

This implements the VIRTIO_SCSI_F_FC_HOST feature by reading the config fields and presenting them as sysfs fc_host attributes. The config change handler is added here because primary_active will toggle during migration.
