host_memory_backend_set_host_nodes() was not validating host-nodes before writing to backend->host_nodes, making QEMU write beyond the end of the bitmap. Fix the crash and add a simple regression test for the fix. While at it, fix memory leak of the list returned by visit_type_uint16List().

Looks like we may have 3.1-rc4 due to some CVE fixes; is this worth including in 3.1 as well?
