H A Dtest-qmp-cmds.c972a110162677fe5155f68a718ec6e999cd059a7 Thu Mar 17 22:48:27 UTC 2016 Eric Blake <eblake@redhat.com> qapi: Fix command with named empty argument type

The generator special-cased

{ 'command':'foo', 'data': {} }

to avoid emitting a visitor variable, but failed to see that

{ 'struct':'NamedEmptyType, 'data': {} }
{ 'command':'foo', 'data':'NamedEmptyType' }

needs the same treatment. There, the generator happily generates a
visitor to get no arguments, and a visitor to destroy no arguments;
and the compiler isn't happy with that, as demonstrated by the updated
qapi-schema-test.json:

tests/test-qmp-marshal.c: In function ‘qmp_marshal_user_def_cmd0’:
tests/test-qmp-marshal.c:264:14: error: variable ‘v’ set but not used [-Werror=unused-but-set-variable]
Visitor *v;
^

No change to generated code except for the testsuite addition.
