From: Eric Blake <[email protected]> The qapi visitor contract allows us to visit a virtual structure, where we don't have any corresponding qapi struct. Most such uses pass NULL for @obj; but these two callers were passing a dummy pointer, which then gets allocated to heap memory but then immediately freed without use. Clean this up to suppress unwanted allocation, like we do elsewhere.
