qom: Clean up error reporting in user_creatable_add_opts_foreach()

Calling error_report() in a function that takes an Error ** argument
is suspicious.  user_creatable_add_opts_foreach() does that, and then
fails without setting an error.  Its caller main(), via
qemu_opts_foreach(), is fine with it, but clean it up anyway.
