hvmloader/smbios: Correctly count the number of tables written

Fixes regression indirectly introduced by c/s 4d23036e709627

That changeset added some smbios tables which were option based on the
toolstack providing appropriate xenstore keys.  The do_struct() macro would
unconditionally increment nr_structs, even if a table was not actually
written.
