hmp: Drop pointless allocation during qapi visit

Browse source 
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.
