qapi: Use returned bool to check for failure (again)

Commit 012d4c96e2 changed the visitor functions taking Error ** to
return bool instead of void, and the commits following it used the new
return value to simplify error checking.  Since then a few more uses
in need of the same treatment crept in.  Do that.  All pretty
mechanical except for

* balloon_stats_get_all()

  This is basically the same transformation commit 012d4c96e2 applied
  to the virtual walk example in include/qapi/visitor.h.

* set_max_queue_size()

  Additionally replace "goto end of function" by return.
