qapi: Fix to reject union command and event arguments

Browse source 
A command's or event's 'data' must be a struct type, given either as a
dictionary, or as struct type name.

Commit dd883c6 tightened the checking there, but not enough: we still
accept 'union'. Fix to reject it.

We may want to support union types there, but we'll have to extend
qapi-commands.py and qapi-events.py for it.

Backports commit 315932b5edb86597adafbd1faa2d29c46499d8c3 from qemu
