_vq_record() stored the result of paddr_guest2host() without checking for
NULL. A guest descriptor with an invalid address causes a NULL dereference
in every virtio driver. Return early on failure; the caller sees zero
descriptors and discards the chain.
The indirect path already performs this check (line 357).
