[PULL 52/53] hw/cxl/mailbox: Use new UUID network order define for cel_uuid

["Michael S. Tsirkin" <mst@redhat.com>]

From: Ira Weiny <ira.weiny@intel.com>

The cel_uuid was programatically generated previously because there was
no static initializer for network order UUIDs.

Use the new network order initializer for cel_uuid.  Adjust
cxl_initialize_mailbox() because it can't fail now.

Update specification reference.
