qapi: Clean up visitor's recovery from input with invalid type
An alternate type's visit_type_FOO() fails when it runs into an
invalid ->type. If it's an input visit, we then need to free the the
object we got from visit_start_alternate(). We do that with
qapi_free_FOO(), which uses the dealloc visitor.
Trouble is that object is in a bad state: its ->type is invalid. So
the dealloc visitor will run into the same error again, and the error
recovery skips deallocating the alternate's (invalid) alternative.
Works, because qapi_free_FOO() ignores the error.
Avoid it instead: free the messed up object with by g_free().
