VIRTIO-134: Spell out details of indirect elements in chains

1) It's implied that a chain terminates with an indirect descriptor (since
   VIRTIO-15) but we didn't spell out that a device MUST NOT continue it.

2) We allow [direct]->[direct]->[indirect], and qemu and bhyve both accept
   it.  Make it clear that this is valid, thus devices MUST handle it.
